The Hulu Terengganu MP said he was notified of the suspension in an April 29 letter from the party’s disciplinary board chairman, which he received via WhatsApp.

“I will not appeal the suspension,” he said in a statement.

Rosol thanked Bersatu for the opportunities it had given him and for its role in his political journey but said recent developments within the party appeared inconsistent with its principles.

He also said the disciplinary board must improve its transparency and ensure a clearer separation among its investigative, prosecutorial and decision-making functions.

“The disciplinary board is increasingly seen as lacking credibility because the same body investigates, brings charges, prosecutes and imposes punishment,” he said.

Last week, Bersatu announced the expulsion of its deputy youth chief and two Kedah assemblymen, while seven others – five MPs and two state assemblymen – were suspended for two terms.

Those suspended were Perak assemblymen Ahmad Man and Syed Lukman Hakim Syed Zin; Lumut MP Nordin Ahmad Ismail; Rompin MP Khalib Abdullah; Tanah Merah MP Ikmal Hisham Abdul Aziz; Ketereh MP Khlir Nor; and Rosol.

The party also issued warnings to Sabak Bernam MP Kalam Salan, Kulim Bandar Baharu MP Roslan Hashim and Kangar MP Zakri Hassan.

Bersatu disciplinary board chairman Radzi Manan said those affected were found to have breached the party’s constitution and its code of conduct and ethics.
