Its information chief, Harris Idaham Rashid, said Saifuddin should leave the party if he has lost trust in the president.

“An open attack like this exposes the intent and motives behind it.

“As such, Bersatu Youth urges the party to take firm and immediate action through its disciplinary board without the need to wait for complaints, investigations or lengthy hearings,” he said in a statement.

Earlier, Saifuddin told Berita Harian that Muhyiddin should step down as Bersatu president, claiming the former prime minister had “lost his leadership quality” and was no longer the same leader he once admired.

The Indera Mahkota MP also accused Muhyiddin of failing to convene party meetings, and also called for the resignation of senior party figures Azmin Ali and Tun Faisal Ismail Aziz.

Harris said Saifuddin’s remarks were a deliberate attempt to undermine the party for his own interests, or those of certain groups.

He said Bersatu Youth wished to remind all party members that no individual was greater than the party, and called on everyone to maintain party discipline.

“Anyone who repeats such behaviour and tries to destabilise this movement is a traitor who must be removed immediately,” he said.
