He was the third child and eldest son of Sultan Iskandar by his first wife, Josephine Ruby Trevorrow, an English woman from Torquay.[10] Ibrahim was appointed as the Crown Prince of Johor on 3 July 1981,[10] and has primarily resided at the Istana Pasir Pelangi since then.[13] These included the 211th Conference of Rulers, where Ibrahim and Abdullah, the Crown Prince of Pahang, represented their fathers in the meetings,[14] among other state functions.[19] The Menteri Besar (Chief Minister) of Johor, Abdul Ghani Othman cited that Sultan Ibrahim and immediate members of the royal family would undertake a mourning period of 40 days.[21] On 30 June 2011, Sultan Ibrahim drove the last train from Tanjong Pagar railway station, having received tuition from Chief Locomotive Inspector Hasnol Azahari Aman of Keretapi Tanah Melayu to enable him to do this.He stated that he wished to do this as his grandfather, Sultan Ismail, had opened the causeway between Singapore and Malaya in 1923, and that it was appropriate for him to drive the last train out of the station.[34] Sultan Johor is noted for advocating religious moderation and has criticised the creeping Arabisation of Malaysian Muslim culture.He would not accept any appointments except for the previously scheduled events and the weekly audiences with the Menteri Besar and the state government of Johor as he wanted to spend his remaining time before the ascension with the royal family.[3][37] During this time, the Conference of Rulers also elected Sultan Nazrin Shah of Perak to a third term as the Deputy Yang di-Pertuan Agong.[40] Occasional reports of alleged criminal misconduct from the 1980s onwards marred Tunku Ibrahim's reputation somewhat, albeit to a much lesser extent than his father, Sultan Iskandar, whose past crimes had received considerable attention from mainstream media.[42][43] In late 1992 to early 1993, Tunku Ibrahim also experienced fallout from the Gomez Incident– in which his father and younger brother, Tunku Abdul Majid were accused of two separate but related incidences of assault which provoked nationwide moral outrage and ultimately resulted in constitutional amendments to allow members of royalty to be prosecuted for criminal wrongdoing.[46] In March 2005, a member of the Malaysian royalty allegedly assaulted a young woman by the name of Yasmin whom he accused of two-timing him with another policeman.[50] The following June, press reports leaked that Tunku Ibrahim had chalked RM26,700 worth of unpaid traffic fines since 2000, causing much embarrassment to the crown prince.[71] Sultan Ibrahim has keen interest in sports, especially polo, which has led him to participate in various tournaments up to the international level.(Brunei), S.P.M.J, S.S.I.J, S.P.M.T, S.M.N, S.P.M.K, S.P.M.P, P.I.S, Sultan Yang Dipertuan Bagi Negeri dan Jajahan Takluk Johor Darul Ta’zim.
