Prime Minister Dr Mahathir Mohamad has brushed off Johor Umno's suggestion that Bersatu president and Home Minister Muhyiddin Yassin be nominated for the state's menteri besar post.

"He has other jobs. We will put up a candidate," said Mahathir, when asked today after launching the Malaysian Autoshow 2019 in Serdang, Selangor.

Bersatu, which Mahathir chairs, has been mandated to take the lead role in Johor Pakatan Harapan.
