Peggy Mitchell

Peggy married Eric Mitchell because she was pregnant with their son Phil Mitchell (Steve McFadden). Eric grew to be a keen boxer, he worked for a gangland boss: Johnny Allen (Billy Murray). This impacted the marriage as Johnny constantly taunted Eric, making him do demeaning jobs because Eric was a better boxer than him. Eric fell in love with a glamorous woman called Maureen Loftus and planned to elope with her, but he changed his mind at the last minute – unable to desert his family, who he grew to resent. Eric took his anger out on Peggy and was often violent towards her and Phil.[2] The abuse eventually ended when Peggy told the police that Eric was involved in a Post Office robbery and he was sent to prison. Peggy considered leaving when her sons, Phil and Grant (Ross Kemp) were teenagers, and once even tried to seduce Johnny, but he turned her down. Eric cheated on Peggy with Claudette Hubbard (Ellen Thomas), who he also intended to run away with, but he changed his mind again, leading to Claudette hating the entire family. Peggy turned to Eric's younger brother Archie (Larry Lamb) because he was there for Peggy when Eric began to abuse her. She tried to save her marriage by having another child in 1975 – her only daughter Samantha (Danniella Westbrook; Kim Medcalf). Her relationship with Eric improved, but only temporarily, and when Kevin Masters (Colin McCormack) employed Peggy to work at his minicab firm, where they began a secret affair. When Eric developed cancer, Peggy gave up work to care for him, but Kevin returned promptly after Eric's death in 1985 and Peggy's children took against him.[2]

Peggy makes her first appearance in Albert Square when her son, Grant, decides to reenlist with the army and returns when her daughter Sam's desire to escape from her family causes her to elope with Ricky Butcher (Sid Owen), at the age of sixteen. Peggy, along with Kevin, tries to persuade Sam that getting married at the age of sixteen will ruin her life, but she is unsuccessful. Peggy later accepts Sam and Ricky's relationship and leaves, after giving the couple her blessing.

Peggy is not seen for three years, during which time her relationship with Kevin ends. She returns to Walford when her sons fall out after Phil's affair with Grant's wife, Sharon Mitchell (Letitia Dean), is revealed. Peggy becomes acting landlady of The Queen Victoria public house and blames Sharon for the affair. Peggy tries to force her out of Walford, resulting in Sharon signing over her share of the pub and leaving the Mitchell family as the sole owners, with Peggy in charge.

Peggy starts dating businessman George Palmer (Paul Moriarty), unaware that he is a criminal involved in illegal money laundering. She instigates a hate campaign against local resident Mark Fowler (Todd Carty) when she discovers he is HIV positive and begins a feud with his mother Pauline Fowler (Wendy Richard). Peggy later realises she was wrong when she is diagnosed with breast cancer. She initially refuses surgery and ends things with George, fearing that he will not be able to handle her illness. However, supported by George and her family, she eventually has a lumpectomy. Peggy and George get engaged but their relationship ends when Phil reveals his criminal nature. Peggy goes on to date local car lot owner, Frank Butcher (Mike Reid), and they become engaged. Peggy has doubts about the wedding when her cancer returns and she has to have a mastectomy, but eventually decides to go through with it. Tension develops between Peggy and Phil when Grant leaves for Rio de Janeiro after a violent fight with his brother. To spite Peggy, Phil sells Grant's share in the pub to local businessman Dan Sullivan (Craig Fairbrass) for £5. Peggy loathes Dan, and the two frequently argue over the running of The Queen Vic, ending with Dan insulting Frank's daughter Janine Butcher (Charlie Brooks), resulting in Frank punching Dan across the face. Eventually, she and Phil call a truce and force Dan out of Walford. Peggy discovers Frank is planning to leave her for his ex-wife, Pat Evans (Pam St Clement), so she shames them by reading Frank's Dear Jane letter to the entire pub and then slaps them both. She throws Frank out and he leaves Walford. Afterwards, Peggy becomes depressed and begins to rely heavily on tranquillisers. When Janine taunts her on Christmas Day about her father moving on, Peggy begins drinking heavily and smashes up the pub with a baseball bat. The next year, Peggy is forced to sell the pub as Frank left her in debt, and is furious to discover the new owner is Sharon.

Peggy begins dating Harry Slater (Michael Elphick), who owns a bar in Spain and convinces her to move there with him. They become engaged but break up when it is revealed that Harry is guilty of sexually abusing his niece Kat Slater (Jessie Wallace) and is therefore the father of Kat's teenage daughter, Zoe Slater (Michelle Ryan). When Phil begins dating Sharon again and becomes joint owner of The Queen Vic, Peggy moves back in. She later becomes sole licensee again when Sharon sells her half of the pub back to her. Peggy is briefly reunited with Frank when she travels to Spain to attend his funeral. She discovers he faked his own death to avoid creditors. While she's in Spain, she shockingly finds Sam working as a lap dancer and takes her home. Peggy later decides to move to Brazil to be with Grant but visits Walford for Sam's wedding to Andy Hunter (Michael Higgs) before returning to Brazil.

When Peggy returns to Walford in 2005, she is furious to discover Sam has lost possession of The Queen Vic, and that the new licensee Chrissie Watts (Tracy Ann Oberman) has framed Sam for her husband Den Watts' (Leslie Grantham) murder. While trying to exonerate Sam and reclaim ownership of the pub, Peggy ignites a feud with Johnny, who also wishes to buy The Queen Vic. Johnny hires a mobster to assault Peggy, but she is saved by her sons, Phil and Grant. They are able to deal with Johnny, secure Sam's release from prison, and return Peggy to The Queen Vic. Peggy begins a romance with Jack Edwards (Nicky Henson), the father-in-law of Peggy's relative Billy Mitchell (Perry Fenwick). However, when Peggy discovers Billy's newborn daughter, Janet Mitchell (Grace), has Down syndrome, she declares that the baby should be put up for adoption, causing friction in her relationship with Jack. Although Peggy comes to accept the baby, Jack breaks up with her and leaves Walford.

Peggy begins a relationship with her brother-in-law, Archie, father of Ronnie (Samantha Womack) and Roxy Mitchell (Rita Simons). They get engaged and Archie begins subtly controlling Peggy. They marry, but it ends a few hours later when it is revealed that Archie lied to Ronnie about her infant daughter's death. Peggy has Archie evicted from The Queen Vic, and tries unsuccessfully to coerce Phil into murdering him. Peggy files for divorce and Archie plots revenge on the entire Mitchell family. When Peggy loses the bail surety she has paid on behalf of her daughter Sam (who breaks the conditions of her bail following coercion from Archie), the Mitchells are forced to use The Queen Vic to gain a collateral loan from Ian Beale (Adam Woodyatt). Archie uses Janine to blackmail Ian into selling him the loan, and when the Mitchells are unable to meet the loan repayment, Archie evicts them and assumes ownership of the pub. However, Archie is murdered on Christmas Day 2009 by an unknown assailant (see Who Killed Archie?). Peggy grieves for Archie, but she and various other members of her family become suspects for his murder. Following a police enquiry, Bradley Branning (Charlie Clements) is posthumously found guilty of the murder, though unbeknown to everyone, the actual murderer is Bradley's wife, Stacey Branning (Lacey Turner), after Archie raped her. In his will, Archie leaves The Queen Vic to Roxy, who reinstates Peggy.

After being disgusted with the state of the Square and learning that a councillor has stood down, Peggy and Pat both decide to run for council and are interviewed by journalist Harvey Freeman (Martin Jarvis). Eventually they both pull out of the election, but Harvey hears of this and individually invites them both out. They both finally discover his two-timing, and humiliate him in punishment. When Phil prevents his daughter Louise Mitchell (Brittany Papple) from contacting her mother, Lisa Fowler (Lucy Benjamin), Peggy interjects and Phil punches her. Believing he is an unfit parent, Peggy takes Louise to Lisa against Phil's wishes. Although Lisa promises to allow Phil visitation, she flees with Louise. Phil blames Peggy for the loss of his child and begins using alcohol and crack cocaine. Peggy tries to stop Phil using crack by locking him in her pub, but Phil escapes and in a drunken bid for revenge, he sets fire to Peggy's pub (see Queen Vic Fire Week). Peggy watches in horror as it is destroyed. Realising her role in Phil's problems, Peggy decides to leave Walford for his sake. After saying tearful goodbyes to her family and making peace with Phil, Peggy takes one last look at The Queen Vic and leaves Albert Square.

In January 2012, Peggy misses Pat's funeral as she is on a cruise, and in 2013, Phil visits Peggy in Cornwall with Ben's baby daughter, Lexi Pearce (Dotti-Beau Cotterill). Three months later, Peggy flies into London to visit Phil in hospital, and encourages him to get rid of Carl White (Daniel Coonan) – an ex-conman who seeks to take over the Mitchell business empire. After, she visits Pat's old house, and leaves a bottle of gin on the doorstep as a way of saying goodbye. In September 2014, Peggy appears in Portugal, telling Ronnie to go back to Walford and stop Phil from marrying Sharon. In February 2015, Peggy returns to the square to confront Dot Branning (June Brown), after her son Nick Cotton (John Altman) cut the brakes on a car and falsely incriminated Phil. She is also in on the secret that Ben's mother and Phil's ex-wife Kathy Sullivan (Gillian Taylforth), faked her own death ten years ago and wants to return to Walford. Before returning to Portugal, Peggy visits The Queen Vic and meets its new landlord, Mick Carter (Danny Dyer), who tells her to "get out of my pub" (which Peggy was known for saying as landlady).

In January 2016, Phil calls Peggy's older sister, Sal (Anna Karen), wanting Louise's (now played by Tilly Keeper) address, and when he goes to her house, Peggy is there, having returned a week earlier. Peggy is disgusted to see that Phil has returned to alcoholism, but does give him Louise's address. She then reveals her breast cancer has returned, and she is dying. Phil tries to admit that he has cirrhosis of the liver, but she refuses to see him again and he leaves. In May, Peggy turns up on Ronnie's doorstep, and the next day Sal arrives with the news that Peggy's chemotherapy is not working and she is dying. A hospital appointment confirms that Peggy's cancer has spread to her brain and it is terminal. Peggy finally faces Phil, who is in recovery from his alcoholism, and admits she is dying. He is upset that she is refusing any more treatment, and takes her on a boat trip on the Thames, and back to their childhood home, to try to make her fight. However, Peggy is not convinced and asks Phil to help her die.

Sharon calls Grant back to Walford, and he persuades Phil not to help Peggy. She tells them both she will not kill herself, and after settling old feuds with Dot, Stacey and Sharon, Peggy receives a vision of her old friend, Pat. She decides she wants to be remembered as a strong woman, not as an invalid, so takes a lethal overdose of pills that she hid from her sons and dies in her sleep that night. Phil is devastated to find her body, and a letter from her urges him to love himself as others love him. Peggy's funeral takes place on 4 July 2016. Phil is due to give a eulogy to her there, but gets too emotional and runs home. Sharon later calms him down by revealing that Peggy was the one who sent Eric to prison when Phil was a child, not corrupt police officers as he was previously told, and that she did it to protect him. Phil later works up the courage to finish his eulogy to Peggy at the wake, and then returns to her grave at the church to finish his goodbyes to her, unaware that Grant has secretly left a rose at the grave.

Hilary Kingsley, author of The EastEnders Handbook (1991), has described Peggy as tough, with a "knack for getting her own way". She adds, "Peggy likes to think she looks much younger [than she is]. She's flash, fast-talking and nobody's fool. She has always done things her own way, and heaven help anyone who crosses her, though her bark's usually worse than her bite."[2]

When Windsor took over the role in 1994, she was unhappy with the way Peggy was being scripted. She has commented, "a few things weren't quite right about Peggy at the beginning. On a purely superficial level, the wig didn't fit right. And the clothes weren't right either. They appeared too downmarket. I was particularly worried about how the character was viewed by the producer and writers. I saw her as much ballsier than they did. I think they envisioned Peggy as this rather sad, vulnerable lady who spent all her time worrying about her children."[5] However, early in 1995, EastEnders acquired a new executive producer, Corinne Hollingworth, who shared Windsor's vision of Peggy. It was Hollingworth who decided that Peggy would be a central character, the new landlady of The Queen Victoria public house, one of the soap's main focal points. Hollingworth stated that Peggy was "not going to be allowed to just sit in some flat polishing her nails".[5] Windsor has said: "It was like a dream. [Hollingworth] let me go out with the costume designer and choose Peggy's wardrobe, which needed to be a lot more flash and upmarket. Corinne and I worked on getting Peggy right and I finally began to believe...".[5]

Windsor has described Peggy as "from the old school, the generation which doesn't put up with rubbish from anybody...She can get through practically anything because she's tough, tough, tough."[5] The character has been classified by Rupert Smith, author of EastEnders: 20 Years in Albert Square, as a matriarch, assuming "papal infallibility. Whatever anybody does — particularly her own children — she knows better."[9] She has also been branded a "battleaxe" by Dave West of entertainment website Digital Spy,[10] and someone who "wears her heart on her sleeve" by Windsor.[11] Family-orientated, Windsor adds that: "[Peggy] loves her family with a passion. Her worst qualities are that she's blinkered, sometimes wrongly passionate about her family."[11]

It has been speculated that Windsor based Peggy on Violet Kray, mother of the infamous East End gangsters, the Kray twins; however Windsor has denied this.[11] Instead, she claims that Peggy is based on women she has seen in East End pubs and her own mother: "women whose hair is great and their outfits are more Walthamstow market, they get it wrong slightly...Some things I've done with Peggy is from my Mum. She was one of those East End snobs. I drew on all of those experiences."[11] In a 2009 radio interview with Dale Winton, Windsor said three people have influenced her portrayal of Peggy: Violet Kray (thus retracting her earlier statement), her own mother, and the actor Mike Reid, who played her on-screen husband Frank Butcher.[12]

In 1996, Peggy featured in a storyline about breast cancer. It was the first time that the soap had given one of its characters the illness, though the issue was covered much less substantially in 1987 as a means of promoting breast cancer screening, when Sue Osman (Sandy Ratcliff) discovered a lump on her breast, which turned out to be benign.

Peggy's breast cancer storyline was devised at the suggestion of a scriptwriter in a story conference session and, according to the production staff, was an idea "that had been knocking about for a long time."[14] In Lesley Henderson's book, Social Issues in Television Fiction, an EastEnders researcher explains that: "A lot of illnesses [...] translate quite readily into strong dramatic material", and the experience of being hospitalised or waiting on test results is something everyone can identify with.[14] The programme sought expert advice on "storyline visuals" from a variety of sources including cancer organisations, breast cancer charities and medical professionals.[14] There were anticipated problems with running a breast cancer story, such as timing, characterisation, casting, and interweaving the plot with other ongoing storylines. A story editor has explained: "EastEnders is perceived as being an issue-led show, but it isn't, it's character and story-led [...] If you haven't got the character to fulfill that storyline then it won't work. You've got to be careful to make sure that the illness actually impacts on the family dynamics and the character development."[14]

Producers decided to use Peggy in the breast cancer storyline, conforming to a soap opera tradition of reserving strong roles for a firmly established middle-aged matriarch.[14] The audience were familiar with Peggy's history, knew that her first husband had died from cancer, consequently making her fear hospitals, and she had: "the right mentality for [the story theme], which was about 'a woman who discovers a lump and then refuses to accept that anything's wrong'. An added factor was that in choosing Peggy the programme could avoid appearing too issue driven, and [the] storyline could be used as a device to expand and develop her characterisation."[14] Additionally, as the causes of breast cancer are not attributable to risky behaviour, the disease was deemed "more attractive" in storyline terms. A member of the EastEnders production team explains:

If you take a character who smokes and they get lung cancer that would seem too issue-driven. The great thing about a character like Peggy is [her breast cancer was] quite unexpected. At the time there were lots of other issues in her life. She was a character who audiences had only seen pulling pints behind the bar. Suddenly she was in a new environment in a hospital and had a huge medical crisis to go through, so that allowed the character to grow and expand in many ways...There was also fairly major moments [...] with Peggy and [her boyfriend George Palmer (Paul Moriarty)]. She thought George wouldn't love her any more after she'd had the operation. We were able to use the illness to take them on a new journey.[14]

In the view of the production team, Peggy's breast cancer was a catalyst, creating new dynamics and tensions amongst existing characters. Realism was also an issue. As a middle-aged woman, Peggy was epidemiologically at higher risk for developing breast cancer.[14] In 2001, it was reported that Peggy's character was one of only a few media portrayals of older females to be given the disease, and source organisations have praised EastEnders for this.[14]

Ross Kemp plays Peggy's son Grant. The issue of whether Peggy's children would discover her breast cancer was used to build tension and create suspense in the viewing audience.

The storyline used elements of suspense, created by the use of "shared secrets" between Peggy and her daughter-in-law Tiffany Mitchell (Martine McCutcheon), who invented elaborate cover stories to mask Peggy's trips to hospital from her sons and partner. Tension was deliberately built for viewing pleasure, posing the questions of whether Peggy's lump was benign or malignant and whether she would die, but also in terms of Peggy's relationships, whether her children would discover the truth or if George would end their relationship. Henderson has suggested that: "such devises [added] pathos to Peggy's treatment path. Audiences [knew] that she [was] terrified and about to discover her biopsy results, but must watch as she is casually castigated by her son Grant for pestering his wife Tiffany to accompany her to 'the dentist'."[14] Hospital scenes were also played for narrative pace to build tension and drama.[14]

Because "radical, body-altering" surgery on a long-running character would cause the production team ongoing problems with continuity, it was decided that Peggy would have a "less visible" lumpectomy, rather than a mastectomy. A member of the EastEnders production team explained: "We have to think about costume and what it's going to look like afterwards and what we're lumbering ourselves with [...] you have to think of that for a long-term character."[14] Additionally, giving Peggy a lumpectomy at that stage of her disease was viewed favourably by source organisations, as it helped to spread a message that a mastectomy is not necessary in all breast cancer cases.[14] However, the storyline was revisited several times over the next few years. In August 1997, Peggy was given the "all-clear" at her follow-up mammogram, and in March 1999 the cancer returned and she underwent a mastectomy, while in 2000 she had a breast reconstruction.[14] It has been reported that Peggy was the first soap opera character to undergo a mastectomy.[15] BBC Production chief executive Matthew Bannister praised Windsor's portrayal of Peggy coming to terms with a mastectomy, commenting: "It's brought a good deal of comfort and help to us and a lot of other people."[16]

Oncology nurses and consultants were involved in the development of the storyline, which was based on a real life case study. In Clive Seale's book, Health and the Media, EastEnders was praised for putting its message across without being "gruelling".[17] It has also been praised for showing "potent scenes" of a woman coming to terms with her diagnosis, scenes that also provided "rare opportunities" to portray a cancer patient "behaving badly" and depicting "ambivalent feelings (such as denial or anger)" — as it had been noted that cancer patients are typically portrayed in the media as "beatific, serene figures".[14] When Peggy had a mastectomy, hundreds of viewers wrote to the BBC to thank producer, Matthew Robinson for tackling "a difficult subject so sensitively".[15] However, not all viewers were impressed with the storyline. Felicity Smart, who had undergone a mastectomy, wrote to the BBC on behalf of the Breast Carer Support Group at St Thomas' Hospital in London to say that emotionally the storyline "hit the spot", but medically it was "hopelessly inaccurate" as according to Smart: "No one pulls pints and wisecracks with customers three days after having a mastectomy."[15]

In 1998, Peggy was romantically paired on-screen with the character Frank Butcher (Mike Reid). Their coupling was part of producer Matthew Robinson's plan to place the focus of the soap back on to the Butcher and Mitchell families, while various other long-running characters were axed following a decline in ratings. The soap was attracting 15.74 million viewers in May 1998, as opposed to rival soap Coronation Street's 16 million.[18]

Played by Mike Reid, Frank had been a regular character in the serial from 1987 to 1994, and had appeared in a recurring role until 1998, when Reid agreed to return full-time. Frank's history on the show included a former marriage to another long-running matriarch, Pat Butcher (Pam St. Clement). Their history as lovers featured prominently in Peggy's narrative in 1998, when, after agreeing to marry Frank, Peggy was wrongly told that Frank and Pat were having an affair. A special two-hander episode aired in November 1998, featuring only Pat and Peggy for the entire duration. It concentrated on Peggy's reaction to the suspected affair, whilst simultaneously addressing Pat's unresolved history with Frank and the apparent destruction of Pat's own marriage to Roy (Tony Caunter), who had also responded badly to the rumours about his wife's infidelity. The episode, written by Tony Jordan, featured what the Sunday Mirror described as one of "the most vicious fights ever filmed by a soap",[19] with both throwing glasses at one another and Pat slapping Peggy across the face exclaiming "You bitch!" and Peggy responding by slapping Pat exclaiming "You cow!".[20] According to press reports, the fight scene between the characters was "so powerful that it had to have scenes and dialogue cut so it could be screened before the 9 pm watershed." Barbara Windsor was reportedly bruised during the filming. Windsor commented, "The writer didn't want a namby- pamby cat fight between two silly girls. We were throwing chairs and bottles and the adrenaline was at a high. When I saw the programme I couldn't believe how good it was. Pam and I were really proud." The Sunday Mirror described it as: "one of the most impressive episodes of all time".[19] In the climax of the storyline, both couples resolved their differences, and their relationships remained intact.

Peggy and Frank were married on-screen on 1 April 1999. A "hen night" was thrown for Windsor with the show's make-up team, and the BBC threw a "massive" party in the show's Albert Square to celebrate the event. Actors Windsor and Reid joined fellow stars, celebrities and TV executives for a celebration on the programme's set in Elstree, Hertfordshire. Windsor admitted she had been so nervous before filming the wedding she was sick on set. She commented, "I broke out in spots and threw up in the vestry. I was very nervous – we were both very nervous. The day you stop getting nervous you can hold your hands up. It shows you care."[16] The soap wedding was filmed in Harrow, North West London in February 1999. A BBC spokesman commented: "It is one of the best weddings Walford has ever seen but it is not problem free. There are a lot of people who do not want to see Frank and Peggy married – Grant being one of them – and it remains to be seen whether they will get through the day without a major upset. And as if the wedding is not gripping enough, there are certainly shocking revelations back at the Vic."[21] In the eventual episode, it was actually Grant Mitchell who persuaded his mother to marry Frank – with whom he had been feuding following his accidental killing of wife Tiffany – after Peggy was having second thoughts, thinking that Frank was only marrying her out of pity.[16] Nearly 20 million viewers watched Peggy and Frank marry.[22]

Together Frank and Peggy ran The Queen Victoria, and were involved in various family and business crises, including a "tug-of-war" for their public house with "cuckoo-in-the-nest" Dan Sullivan (Craig Fairbrass).[23] After taking time off in 2000 due to ill-health, Reid announced that he was quitting the soap in May 2000.[23] After Reid publicly declared that he would love Frank to have a last fling with Pat before he left, EastEnders' bosses granted his wish and an affair was scripted.[24] The pair enjoyed a liaison on a Spanish beach during a week-long August special set on the Costa Blanca, which saw Frank and Peggy go away with Pat and Roy and Terry and Irene Raymond (Gavin Richards and Roberta Taylor).[24] A BBC spokesperson said: "Pat is obviously incredibly torn between her love for her husband, Roy, and her old feelings for Frank. She's been hurt by Frank in the past, but she's coming to realise that she still has strong feelings for him and he has made no secret of his soft spot for her. I can confirm they do enjoy a romantic kiss on the beach."[24] On-screen, Pat and Frank's affair continued until they decided, in November 2000, to elope. In the specially extended episode marking Frank's official exit — which aired on 2 November 2000, but was Guy Fawkes Night in the on-screen events – Peggy discovered the affair amidst Frank's attempt to retrieve a letter of confession, following Pat's change of heart.

After revealing their deception to a busy Queen Victoria public house, Peggy slapped both Pat and Frank, rebuffed Frank's attempt at reconciliation and left him to depart alone.[25] In December 2000, Ian Hyland of the Sunday Mirror voted the scene in which Peggy slaps both Pat and Frank as one of the "TV fights of the year", saying "It was Peggy's speech which really made it a Bonfire Night to remember. But the slaps were equally well dispatched."[26] Commenting on Reid's exit, Windsor has said, "We fell out when I found out he was leaving because it was a shock for me. I was really upset. I've known him 30 odd years and I really like working with him. We had a great relationship as friends as well as performers. I got my own back when I had to slap him after I found out he was fooling around with Pat. I did the slap twice as I didn't think I did it hard enough the first time."[11]

Windsor took a two-year sabbatical in 2003, having contracted the Epstein-Barr virus.

Peggy was written out of EastEnders in 2003, sent to live in Rio de Janeiro with her son Grant for two years, while Windsor took a sabbatical from the show after being diagnosed with the Epstein-Barr virus. Windsor had previously never taken more than two weeks leave annually during her eight years on the show, as Peggy was considered such a central character to the series.[27] Windsor's absence was originally only supposed to be a year long. She stated at the time: "This has been a very hard decision for me to make because I'm so happy here on EastEnders but it's been a long time without a proper break. I just feel some time off would be good for me and for the character too."[28] Louise Berridge, then EastEnders' executive producer, commented: "Barbara has been an absolute trouper for more than eight years on this show. We hope she has a great time and look forward to bringing her back with a big story in 2004."[28]

Although Peggy did return briefly in 2004 to attend her daughter Sam's wedding to Andy Hunter (Michael Higgs), it was not until 2005 that she resumed her role as a series regular. Her full return was announced in January 2005, with John Yorke, the BBC controller of continuing drama series, stating he was "delighted" as "[Peggy] is a hugely loved character and one we think will be stirring things up from the moment she steps back into Walford."[27] Windsor said that she was "over the moon" to return, adding: "I had a great time when I came back to film for a couple of weeks recently. It really reminded me that the square is where I feel at home."[27] BBC executives hoped that Peggy's return would help to revive EastEnders' ratings.[29] Her absence coincided with a two-year ratings slump for EastEnders, with David Liddiment in The Guardian drawing direct correlation between her return and the show's "ratings rejuvenation".[30] The episode in which she returned was watched by 10 million viewers, winning EastEnders a 47% audience share in the timeslot.[31]

In March 2008, the BBC announced that Larry Lamb had been cast as Archie Mitchell, the brother of Peggy's late husband Eric. Archie was scripted as a love-interest for Peggy and Peggy's backstory was retconned to incorporate a romantic history with Archie.[32] Portrayed as an adulterous villain, Archie began controlling Peggy, changing her clothing and her hair style and instructing her on how to behave.[33]

In 2009 Peggy ran as an independent candidate in the local council elections against Archie's wishes. Writers wanted a storyline that allowed Peggy to stand up for her beliefs, and felt that running for local government would allow her to speak passionately about the community.[34] After a scene showed Janine Butcher (Charlie Brooks) asking Peggy, "Where would Tony Blair have been without Alastair Campbell?", Campbell responded by giving advice to Peggy in a video blog.[35] A response from Peggy was then recorded, thanking Campbell for his input.[36] Peggy pulled out of the election at Archie's request ahead of their wedding, however the storyline set up a later episode in which Boris Johnson made a guest appearance in EastEnders.[37] On 1 October 2009, Johnson appeared in the show as himself, visiting Walford and The Queen Victoria and conversing with Peggy. Johnson commented on his appearance: "It was, of course, a tremendous honour to step inside that most venerable of London landmarks, The Queen Vic, and share a scene with another of the capital's icons, the fabulous Barbara Windsor."[38] Executive producer Diederick Santer stated: "We couldn't let the visit pass without the Mayor entering London's most famous pub, The Queen Vic, and meeting its formidable and politically active landlady Peggy Mitchell."[38] The episode was watched by 8 million viewers, winning EastEnders a 38% audience share in the timeslot.[39]

Peggy and Archie's wedding was filmed on location in North London in January 2009 and was screened on 2 April 2009 that year in an hour-long special. To promote the storyline, EastEnders screened a trailer showing Peggy being assembled in her wedding outfit by a robot, which symbolised Archie's control of her.[40] Realising the extent to which Archie had been controlling and trying to change her throughout their engagement, Peggy gave him an ultimatum at the altar: he either accept the real her, or call the wedding off. Archie chose to marry her, though Tim Teeman for The Times commented: "'[T]he real Peggy' is a hazy concept: there’s Peggy the big-hearted East End landlady and Peggy the crone famous for rasping 'Get ahht my pub' to anyone who crosses her path. For someone into evil mind control, Archie has brilliant taste. The wedding outfit he had chosen for Peggy was much nicer than the tatty net curtains that even Miss Havisham would have rejected that the 'real Peggy' chose to marry in."[40] Peggy and Archie's wedding was watched by 10.6 million viewers, winning EastEnders a 48% audience share. A further 1.2 million viewers watched the episode's repeat on BBC Three at 10 pm.[41] However, the marriage lasts only as long as the reception; when Peggy realises Archie has been manipulating other members of his family, Peggy throws him out and a feud ignites between Archie and the Mitchell clan.

Peggy resumes her plan to run for council in 2010, but is furious to discover that Pat is also running. The storyline introduces the character of Harvey Freeman, played by Martin Jarvis, a freelance journalist who is reporting on the election. Harvey is a potential love interest for both Peggy and Pat, and causes friction between the friends.[42]

On 28 October 2009 it was announced that Windsor had quit the show and would leave in 2010 after 15 years.[43] She said: "EastEnders has been wonderful to me and it's no secret that it changed my life all of those years ago. I'll be so sad to leave Peggy behind; she's such a wonderful character to play. I have had the pleasure of working with a marvellous cast and crew and have made many lasting good friends. To have had the honour of showing the Queen around the set is something that will stay with me forever."[43] Executive producer Diederick Santer said: "Barbara has contributed so much to EastEnders over the last 15 years, plus countless episodes, and countless amazing storylines. Peggy Mitchell is a truly iconic character, and along with Steve McFadden and Ross Kemp, Barbara has made the Mitchells the premier family of British soap."[43] Windsor filmed her final scene on 16 July 2010.[44][45] Peggy's final episode, which aired on 10 September 2010, was preceded by a number of television trailers in August and a new section on the EastEnders website dedicated to the character.[46][47] The episode ended with a special reworking of the piano version of the EastEnders theme tune known as "Julia's Theme", called "Peggy's Theme".[48] Tribute was then paid to her in a clip programme, Peggy Mitchell: Queen of the Vic. Peggy's final episode attracted 10.1 million viewers, and was the second most-watched programme in the week of 6–12 September.[49]

At the recording of the new series of The Rob Brydon Show for BBC Two, Brydon asked if Windsor would consider returning, to which Windsor replied, "Never say never".[50]

After making three separate returns in September 2013, September 2014 and another in February 2015 to commemorate 30 years of EastEnders in EastEnders Live Week, Windsor made an unannounced return to EastEnders in 2016, appearing in the episode broadcast on 15 January. After this, it was announced that the character was to be killed off, losing her battle with breast cancer. The scenes were filmed in secret in November 2015, following Windsor's personal decision for Peggy to be killed. She said: "Peggy is a character close to my heart but I made the decision a while ago that I need to say goodbye to Peggy once and for all as otherwise she will always be there, urging me to go back and that is something I need to shut the door on. After thinking long and hard about it, I realised that it is time for me and the audience to say our final farewells to the lady who I have loved for many years and I thought that whilst [executive producer Dominic Treadwell-Collins], who I adore, is still in charge I want him to be the one to oversee it. I am grateful that Dominic has accepted my decision and together, since late last summer, we have been secretly plotting Peggy’s last scenes."[51][52]

Treadwell-Collins said, "when [Windsor] told me her decision back in the summer [2015], we both had a little cry before getting excited about how Peggy Mitchell, the matriarch to end all matriarchs could bid her final farewell to Albert Square. In Peggy Mitchell, Barbara has created one of the greatest ever characters on British television, someone who has become as synonymous with EastEnders as The Queen Vic itself. So this is the end of an EastEnders era. But it is also an opportunity to send Peggy Mitchell out in style in what will be one of the most heartbreaking, uplifting and epic exits an EastEnders character has ever had. We can't wait to have Barbara back at EastEnders, even if it is for the final time. The most professional of professionals on set and off, and a true friend, we have all been working harder than ever to make Barbara and Peggy Mitchell proud."[51] Windsor resumed filming on 21 March 2016.

On 3 May 2016, it was revealed that Peggy would refuse treatment and decide to spend time with her family. Windsor said it was a "special week" of episodes with "lots of surprises" that would be "a perfect ending for Peggy".[54] Peggy's final scenes aired on 17 May 2016;[55] however, her voice was heard in the following episode, which aired on 19 May 2016. Peggy received final credits in white on a black background.
