[3] On 29 September 2012, Johor Menteri Besar Abdul Ghani Othman made the announcement that Tunku Idris had been named as the state's regent while the Sultan and Crown Prince were not present.

At the declaration ceremony held at Istana Pasir Pelangi in Johor Bahru, the Menteri Besar recited the proclamation.

On the other hand, he will be named as the Regent of Johor when the Crown Prince, who is absent at the moment, returns to the state on 19 October.

He posted an Instagram Story with the hashtag "PRU15" and a poll asking whether he should run for the Muar or Mersing parliamentary seat, according to a report by Sin Chew Daily.

When the prince witnessed the destruction caused by the floods in Kelantan, Pahang, and Perak, he claimed he felt compelled to do his part to aid the victims.
