BN's demise in the east

In June 2018, the four Sarawak BN component parties - Parti Pesaka Bumiputera Bersatu (PBB), Sarawak United Peoples’ Party (SUPP), Parti Rakyat Sarawak (PRS) and the Progressive Democratic Party (PDP) - withdrew from the coalition that they helped form in 1974, thus eliminating BN in Sarawak.

Now known as the Gabungan Parti Sarawak (GPS), the new regional coalition has 18 MPs after Sri Aman MP Masir Kujat quit the coallition on March 7, 2018, to join Parti Sarawak Bersatu (PSB).

PSB formerly known as the United People's Party (UPP), is a splinter Sarawak United People's Party (SUPP).

Meanwhile in Sabah, the state BN component parties - Parti Bersatu Sabah (PBS), Parti Bersatu Rakyat Sabah (PBRS) and United Pasokmomogun Kadazandusun Murut Organisation (Upko) - had left the coalition.

PBS and PBRS have joined forces with Parti Solidariti Tanah Airku Rakyat Sabah (Star) to form a Sabah-based opposition coalition known as Gabungan Bersatu Sabah (GBS). Collectively, GBS has three MPs.

Upko forged a pact with Warisan at the state level. Upko has one MP.

While BN is no more in Sarawak, Umno still has one MPs in Sabah - Bung Moktar Radin (Kinabatangan).
