Tom Usher, the youngest member of council and cabinet member for Children and Families, lost a selection contest in his Liscard Labour branch in October to Dave Brennan by 21 votes to 30.[18] This was criticised by Independent group leader, and former Labour councillor, Moira McLaughlin who perceived Usher as having been “booted out by the hard-left”. Liscard labour chair Edwina Doyle dismissed this notion putting the result down to Usher being “a bit younger and less experienced [than Brennan]”. In January 2020, he was selected to contest the neighboring, Conservative held, ward of Wallasey.[19]

Conservative councillor Chris Blakeley died of cancer on 15 January.[20] A casual vacancy was announced on 6 February with the seat to be filled at the upcoming election when Blakeley's term was due to end.[21] Simon Mountney, who had served alongside Blakeley as a fellow ward councillor from 2004 to 2014, was selected as the Conservative candidate in March.[22][23]

A leaked internal Labour report released on 3 March 2020 predicted severe loses for the party at the upcoming local elections across the country.[33] Wirral, however, was one of only two authorities (the other being Burnley) seen as a possible gain for Labour with Wirral being the only positive prediction under all models used within the report.[34]
