The prime minister must be a member of the House of Representatives, who in the opinion of His Majesty the King, commands the support of a majority of members. The Cabinet is chosen from members of both houses of Parliament. The Prime Minister is both the head of cabinet and the head of government. As a result of the 2018 general election Malaysia was governed by the Pakatan Harapan political alliance, although Prime Minister Mahathir Mohamad resigned amid a political crisis in 2020. In March 2020, the Perikatan Nasional coalition formed under Prime Minister Muhyiddin Yassin, before Muhyidden lost majority support and was replaced by deputy Prime Minister Ismail Sabri Yaakob, a veteran politician from UMNO, in August 2021.
