Former Batu Kawan Umno vice-chairman Khairuddin Abu Hassan has lodged a police report against Dewan Rakyat speaker Pandikar Amin Mulia for threatening the MPs.

This is over Pandikar's remark that former deputy prime minister Muhyiddin Yassin and former Umno ministers Shafie Apdal and Ahmad Husni Hanadzlan may have broken their purported oath of secrecy to cabinet.

"As a Malaysian, I believe that Pandikar's statement was a form of threat and intimidation that (prevents) them from carrying out their duty, to speak in Parliament as elected representatives," he said in police report lodged at Jalan Dang Wangi police station today.

Pandikar's move is an attempt to stop parliamentary democracy, he alleged.

He also urged the police to probe Jaringan Melayu Malaysia (JMM) and Sahabat N87 Federal Territory branch, which lodged police reports against the trio on Oct 28 and Oct 29 respectively.

Khairuddin, who recently quit Parti Pribumi Bersatu Malaysia (Bersatu), alleged that the action taken by the two NGOs was tantamount to criminal intimidation.

"This was also (a form of) intervention to the smooth running of parliamentary democracy." 

He wanted these parties to be probed under Section 506 of the Penal Code for criminal intimidation and Section 124C of Penal Code for being detrimental to parliamentary democracy.

On Oct 27, Pandikar said the trio might have broken their oaths of secrecy to cabinet when debating Budget 2017 in the House.

"What I heard the other day is that the cabinet's decision had not been carried out. That is (secret) cabinet information," Pandikar told a press conference then.

Muhyiddin had highlighted in Parliament how the cabinet was not consulted on the formation of 1MDB and had been kept in the dark about its finances until the scandal broke the news.

Husni had questioned why 1MDB, a wholly Finance Ministry-owned sovereign fund, was formed, and asked how its scandals would affect Malaysia's image.
