Four decades in government
Muhyiddin was born in Muar in 1947 and entered Parliament in 1978. He served as Johor’s Menteri Besar from 1986 to 1995, then held federal portfolios including domestic trade, agriculture, international trade, education and home affairs.
As Najib Razak’s deputy prime minister from 2009, he was one of UMNO’s most senior leaders. He was removed from the cabinet in 2015 after publicly raising concerns about 1MDB, expelled from UMNO and became a founding leader of BERSATU.
His path from UMNO deputy to BERSATU founder explains why the 2020 government was not simply a continuation of either the pre-2018 BN administration or the PH cabinet elected in 2018.
The 2020 change of government
BERSATU joined Pakatan Harapan and won federal power in 2018. Muhyiddin became home minister. In February 2020, the coalition fractured after Mahathir’s resignation and a realignment commonly known as the Sheraton Move.
The Yang di-Pertuan Agong appointed Muhyiddin prime minister after consultations intended to determine who was likely to command majority confidence in the Dewan Rakyat. The new Perikatan Nasional administration took office without a general election, making parliamentary legitimacy a persistent issue throughout its life.
The constitutional question was who could command confidence in the existing Dewan Rakyat, not which bloc had won the most votes in 2018. That distinction is the key to understanding the change of prime minister without a new nationwide vote.
Government during the pandemic
Within weeks, COVID-19 became the government’s overriding challenge. A nationwide Movement Control Order began in March 2020. The administration announced the PRIHATIN economic package and later recovery measures to support households, workers and businesses through restrictions and recession.
Early public-health success was followed by renewed outbreaks, strained hospitals and repeated changes to movement rules. A state of emergency in 2021 suspended Parliament for several months, producing controversy over oversight even as vaccination and the National Recovery Plan expanded.
The timing compressed two different crises. Muhyiddin took office in early March 2020, and the nationwide Movement Control Order began on 18 March. The new administration’s legitimacy debate therefore unfolded while public-health operations were disrupted.
Loss of majority support
Muhyiddin’s coalition depended on a narrow and shifting majority. By August 2021, withdrawals of support made his position untenable. He resigned on 16 August, explicitly linking the decision to the constitutional requirement that a prime minister retain the confidence of the Dewan Rakyat.
His legacy is inseparable from the pandemic: emergency controls, welfare support and vaccination on one side; political uncertainty and contested accountability on the other. His route to office also accelerated Malaysia’s era of fluid coalitions.
His own resignation address explicitly invoked Article 43(4) after support was withdrawn. It is unusually direct primary evidence for how parliamentary confidence, rather than the expiry of an electoral term, can end a premiership.
