According to Johor Royal Court Council president Dr Abdul Rahim Ramli, the appointment was made in accordance with Clause 9 (1)(d) and (3) of the Johor State Constitution 1895.

In a statement uploaded on Sultan Ibrahim’s Facebook page, he said the ruler had consented to the appointment at Istana Bukit Serene on the advice of the council.

“This appointment shall continue for the duration of His Majesty’s reign as Yang di-Pertuan Agong,” Rahim said.

He said Sultan Ibrahim also consented to the title of “His Royal Highness Tunku Ismail, the Regent of Johor”, which should be used in all government matters, including letters, speeches and prayers.

Tunku Ismail, who was born on June 30, 1984 here, is the eldest of six children of Sultan Ibrahim and the Permaisuri of Johor, Raja Zarith Sofiah Sultan Idris Shah.

Before his appointment today, Tunku Ismail had been appointed as Regent on several occasions, the most recent being on June 16, 2022, when Sultan Ibrahim took a brief respite from his administrative duties.

Tunku Ismail married Che’ Puan Mahkota Khaleeda Johor on Oct 24, 2014 and they have two sons and two daughters – Tunku Khalsom Aminah Sofiah, Tunku Iskandar Abdul Jalil Abu Bakar Ibrahim, Tunku Abu Bakar Ibrahim and Tunku Zahrah Zarith Aziyah.

Sultan Ibrahim will begin his reign as the 17th Yang di-Pertuan Agong for a five-year term from Jan 31.
