2023 Sabah political crisis
The 2023 Sabah political crisis or widely reported on local media as Langkah Kinabalu or the Kinabalu Move, began on 6 January 2023, when the state government of Sabah led by Gabungan Rakyat Sabah (GRS) collapsed when its coalition party Barisan Nasional (BN) withdrew its support. The Leader of UMNO Sabah, a component party of BN, Bung Moktar Radin, Kinabatangan Member of Parliament (MP) and Lamag Assemblyman, cited a lack of confidence in the leadership of Chief Minister of Sabah Hajiji Noor in the withdrawal. UMNO Sabah want to change support from supporting GRS coalition to supporting the WARISAN Plus coalition. On 9 January, both Malaysian leaders, prime minister Anwar Ibrahim and deputy prime minister Ahmad Zahid Hamidi travelled to Kota Kinabalu to meet with Sabah political leaders. This crisis resulted in the approval of the Anti-Switching Parties Law in Sabah (approved in 25 May 2023). As of 6 February, there have been no changes in the status quo regarding the government of Sabah, following the decision of 5 UMNO MLAs who publicly supported Hajiji despite Bung's decision, and a reshuffle of the state cabinet on 11 January as a result. As of 25 May 2023, Sabah State Legislative Assembly finally approved the Anti-Switching Parties Law (Anti-frogs habit). Background
