2020 Malaysian political crisis is a political crisis in Malaysia that has led to the resignation of Mahathir Mohamad as the seventh prime minister and the appointment of Muhyiddin Yassin as the eighth prime minister. It also saw the ousting of the incumbent coalition government of Pakatan Harapan after having ruled for 22 months following their victory in the 2018 Malaysian general election.
The crisis started when several political parties joined forces and tried to form a new government by claiming majority seats in the Dewan Rakyat, the lower chamber of the Parliament of Malaysia, without going through an election. It was accomplished through the withdrawal of the Malaysian United Indigenous Party (Bersatu) from the Pakatan Harapan coalition and through the support of several MPs from the People's Justice Party (PKR) who left the party. The prime minister, Mahathir Mohamad, resigned as a result.
The Yang di-Pertuan Agong, Abdullah of Pahang, then met with all MPs and political party leaders to gauge their support for a new prime minister. He ultimately appointed the president of Bersatu, Muhyiddin Yassin, as the prime minister. Muhyiddin announced that his coalition government will be called Perikatan Nasional.
Four states; Johor, Malacca, Perak and Kedah also experienced changes in the respective state governments as Perikatan Nasional gained majorities in the state legislative assemblies.
