A combination of factors, including Muhyiddin's decision to pull out his own party (BERSATU) out of the Pakatan Harapan (PH) coalition,[2] the sacking of Mohamed Azmin Ali and Zuraida Kamaruddin from People's Justice Party (PKR) for initiating the "Sheraton Move"[3] and the resignation of nine other Members of Parliament (MPs) aligned to Azmin from PKR,[4] resulted in the ruling coalition losing a simple majority in the Dewan Rakyat, leaving itself hung.

Following the leadership vacuum, the Yang di-Pertuan Agong summoned all MPs to the Istana Negara (National Palace) on 26 and 27 February to gauge their support for a new prime minister.

On 28 February, the National Palace stated that none of Prime Minister's candidates, namely Mahathir, Anwar, Muhyiddin or the self-nominated Bung Moktar Radin, obtained a simple majority in the Dewan Rakyat to form a government.

[8] Sarawak Chief Minister Abang Johari Openg later announced that GPS is not a part of the newly created Perikatan Nasional (National Alliance) coalition but a party that provides confidence and supply to Muhyiddin.

On 8 July 2021, the UMNO made an official announcement to withdraw its supports towards the Muhyiddin government,[10] citing the mismanagement of the COVID-19, the misuse of Emergency Declaration, and so on.
