Muhyiddin Yassin has confirmed that he wants the 1MDB board of directors to resign and for the police to probe them.

"This is my personal view," he told reporters when met in Parliament.

He also disclosed that his speech, a recording of which was uploaded onto YouTube , was made at a closed-door event.

Asked how Prime Minister Najib Abdul Razak responded to this, Muhyiddin shrugged, flashed a grin and replied: " Tiada apa-apa (there was nothing)."

"It is just my (present) statement," he added.

Speaking to reporters after Najib tabled the 11th Malaysia Plan, Muhyiddin however dismissed what he said was anything new.

"This is not new, it has been said outside," he said.

He also said the closed door event was meant to better inform party members about the situation.

"What is important is that we find a solution to this matter," he added.

Although Najib has urged the public to be patient and wait for the Auditor-General's report on 1MDB, Muhyiddin told the Umno training session in Janda Baik that he disagreed.

"I told the prime minister, sack all those guys, the board (of directors) of 1MDB.

"They should be sacked since because of them, the prime minister has to shoulder the burden. Yet, they have not been sacked," he said in the video uploaded by former New Straits Times editor Firdaus Abdullah.

Others refuse to comment

The 7-minute video clip showed that Home Minister Ahmad Zahid Hamidi and Deputy Finance Minister Ahmad Maslan were also at the event.

Muhyiddin said stern action must be taken against the 1MDB top bosses if Putrajaya wants to convince the public that it is serious.

"If not, this will be a burden and will bring our downfall.  We have to take action, we cannot give them more time," he said

1MDB's board of directors is led by Lodin Wok Kamaruddin and comprises Arul Kanda, Shahrol Azral Ibrahim Halmi, Ismee Ismail, Ong Gim Huat and Ashvin J Valiram.

When met in Parliament, Ahmad and Defence Minister Hishammuddin Hussein refused to comment on the video clip.
