The state government is headed by a "Menteri Besar" (Chief Minister), assisted by an 11-member Executive Council (Exco) selected from the members of the Perak State Legislative Assembly. The 59-seat Assembly is the legislative branch of Perak's government, responsible for making laws in matters regarding the state. It is based on the Westminster system. Members of the Assembly are elected by citizens every five years by universal suffrage. The Chief Minister is appointed on the basis of his or her ability to command a majority in the Assembly. The majority (35 seats) is currently held by Perikatan Nasional (PN) 13 days after Pakatan Harapan government collapse.
