Tunku Ismail Idris

Tunku Ismail completed his early education at Sekolah Sri Utama and Sekolah Rendah Kebangsaan St. Joseph in Johor Bahru. He subsequently received lower secondary education at the Australian International School in Singapore and continued with his higher secondary studies at Hale School in Perth, Western Australia, until 2002.[2][3] Tunku Ismail is the eldest among six siblings. Like his father, Tunku Ismail has no tertiary (academic) qualification.

Tunku Ismail was appointed Raja Muda (literally means "Younger King," but taken to mean as second Heir Apparent or son of the Crown Prince) on 8 April 2006 by his grandfather, the late Sultan of Johor, and placing him second in line to the throne (Now first in line after the passing of Sultan Iskandar).[2][3] Tunku Ismail was appointed as the Tunku Mahkota of Johor on 28 January 2010.[4]

His Royal Highness the DYAM Tunku Mahkota (Crown Prince) of Johor, Tunku Ismail Idris ibni Sultan Ibrahim has been appointed as the President of Johor Football Association (PBNJ). The EGM held in Johor Bahru saw the Crown Prince appointed as the new President replacing the former, Jais Sarday. Among his plans to help bring back Johorean football to its former glory, the Crown Prince merged the Johor teams (which previously were Johor FC, MBJB and MP Muar) into only one where all of the players wear the Jengking (Scorpion) Team Jersey. .

Tunku Ismail's leadership on the club Johor Darul Ta'zim F.C also oversaw its success as the first Southeast Asian club to lift the AFC Cup in 2015.[13]

In 2014, the Football Association of Malaysia (FAM) appointed the Tunku Ismail Sultan Ibrahim as an advisor to the previous FAM president, his uncle, Sultan Abdullah of Pahang. Tunku Ismail assisted and worked hand in hand with FAM in improving the quality of football within the country, particularly with the national team as well as the junior teams.

As predicted, there were several concerns about the news, particularly with Tunku Ismail having lost the FAM presidency election to Tengku Abdullah earlier that year. Besides that, he had been extremely vocal with his criticisms on the nation's footballing body. However, the then Johor FA president was extremely optimistic about the new role, claiming that he will only be pushing for the betterment of football within the country.[14]

He was elected as President of FAM for a short term from 2017-2018.

On 24 October 2008, reports surfaced about a confrontation and a royal scuffle which allegedly occurred in a nightclub at Crowne Plaza Hotel in Kuala Lumpur between two princes. Tunku Nadzimuddin, a member of the Negeri Sembilan household, filed a police report accusing of a Johor royal whom he identified the culprit to be Tunku Ismail; for initiating the confrontation and assaulting him in the face and head. A friend of Tunku Nadzimuddin, Shamshudhuha Ishak, a lawyer, filed another police report accusing of Tunku Ismail's bodyguards of assaulting him and losing two teeth in the process.[15]

The following September, Tunku Nadzimuddin lodged a complaint against the police and the Attorney-General chambers for not responding to the police report that he had made earlier for a RM50 million monetary settlement over the alleged episode. In a press interview, Tunku Nadzimuddin claimed that he was roughed up by Tunku Ismail and his bodyguards after the a friend of Tunku Ismail called Tunku Nadzimuddin that he had wanted to apologise over a bottle-throwing incident, while Tunku Nadzimuddin was partying. Tunku Nadzimuddin looked for Tunku Ismail with Shamshudhuha, but they quickly assaulted by Tunku Ismail's bodyguards. Shamshudhuha was beaten unconscious, while Tunku Nadzimuddin was threatened by Tunku Ismail with a pistol pointing to his head, and led to a hotel room where they were confined. The police later arrived after Tunku Nadzimuddin called for his mother. The Johor royalty denied Tunku Nadzimuddin's claims, and stated that Tunku Ismail was barred from meeting Tunku Nadzimuddin that night for security reasons.[16][17]
