Perikatan Nasional chairperson Muhyiddin Yassin said the coalition's 50 MPs support for prime minister candidate Ismail Sabri Yaakob is conditional.

Muhyiddin said the cabinet must not include any ministers that are facing criminal charges.

"If appointed as prime minister by the Yang di-Pertuan Agong, he (Ismail) must ensure that his cabinet ministers are among those who are with integrity, responsible, and free from any criminal charges in court," he said in a statement today.

Among Umno leaders who are facing ongoing court cases include party president Ahmad Zahid Hamidi, who had led the faction of 15 MPs calling for Muhyiddin's resignation, and former premier Najib Abdul Razak.
