The United Sarawak Party (, abbreviated PSB) is a multi-racial political party based in the state of Sarawak. In 2021, PSB managed to retain their four seats (Batu Lintang, Engkilili, Ba'kelalan and Bawang Assan), making it the new opposition party in Sarawak, replacing Pakatan Harapan which only won two seats (Pending and Padungan, all under DAP). History Formation as United People's Party (UPP) The party was initially founded as United People's Party and officially launched on 17 August 2014 as a new symbol of change and unity for the Chinese community of Sarawak with its headquarters based at Kuching. The UPP was actually a splinter party of Sarawak United People's Party (SUPP) set-up by the Second Finance Minister for Sarawak, Wong Soon Koh along with his supporters following a leadership tussle of the party then and it started as a pro-Barisan Nasional (BN) political pact However the hopes that the UPP would join BN were objected by the coalition leadership. UPP rejected Parti Pesaka Bumiputera Bersatu (PBB)'s suggestion that UPP should dissolve to pave the way for its members to join other Sarawak BN component parties arguing that they have over 26 full-fledged branches with 30,000 members and that UPP was able to raise RM38 million (US$9.3 million) for an education fund in less than a fortnight. UPP's ability to raise significant funds is widely attributed to the support they enjoy from Sarawak's powerful timber tycoons. A Memorandum of Understanding (MoU) was made between UPP and SUPP of BN for the division of seats to be contested in the 2016 Sarawak state election which saw UPP win five out of seven seats it was allocated. UPP however cancelled the MoU with SUPP after the 2016 state election. Both rival parties again signed MoU for collaboration in the 2018 general election (GE14). After the GE14 which saw the downfall of BN federal government, the state BN components quit and formed themselves as the new Gabungan Parti Sarawak (GPS) coalition without UPP. Re-branding as Parti Sarawak Bersatu (PSB) UPP was re-branded to United Sarawak Party or Parti Sarawak Bersatu (PSB), after an Extraordinary Delegates Conference (EDC) on 8 December 2018. The party's name change and new logo was approved by the Registrar of Societies (RoS) in 2019.
