Sabah Democratic Party

It was an ethnically-based party striving to voice the rights and advance the development of Kadazan-Dusun-Murut (KDM) populations of Sabah and the Orang Asli of Peninsular Malaysia.

PBS had won a majority in the Sabah State Legislative Assembly, but the defections allowed BN to form government.

[1] Part of the enticement offered by BN to the defectors was the promise of a rotating Chief Ministers of Sabah post, which Dompok held from 1998 to 1999.

[2] PDS was renamed as United Pasokmomogun Kadazandusun Murut Organisation (UPKO) on 8 August 1999, taking the same UPKO acronym of the defunct original United Pasokmomogun Kadazan Organisation, which was formed and dissolved in the 1960s.

[3][4] The party was re-branded again as United Progressive People of Kinabalu Organisation while maintaining its original UPKO acronym and opening party membership to other races than KDM in 24 November 2019.
