Parti Pesaka Bumiputera Bersatu (PBB)
President: Tan Sri Adenan Satem
The state Barisan Nasional lynchpin holds nearly half, or 35 of the former 71-seat Sarawak state assembly. In both the 2006 and 2011 elections, the party made a clean sweep of all of the seats it contested.
Sarawak United People’s Party (SUPP)
President: Datuk Dr Sim Kui Hian
Sarawak’s oldest political party, formed in 1959, was battered in the last state elections. Adding to its woes, a split led to the birth of the United People’s Party, which took with it four assemblymen, leaving SUPP with just two.
Sarawak Progressive Democratic Party (SPDP)
President: Datuk Seri Tiong King Sing
SPDP won six seats in 2011 but now has none. Five assemblymen left to join the breakaway Teras, and another quit to join the Sarawak Workers Party.
Parti Rakyat Sarawak (PRS or Sarawak People’s Party)
President: Tan Sri Dr James Masing
PRS was set up in 2003 in the wake of the de-registration of Parti Bansa Dayak Sarawak (PDBS). It currently holds eight state seats.
United People’s Party (UPP)
Set up in 2014 as a breakaway of SUPP. It has four state assemblymen, all former SUPP representatives.
Parti Tenaga Rakyat Sarawak (Teras, or Sarawak People’s Energy Party)
Set up in 2014, Teras is an offshoot of SPDP and is led by former SPDP president Tan Sri William Mawan Ikom. It now has five state assemblymen.
Democratic Action Party (DAP)
State chairman: Chong Chieng Jen
The fortunes of Sarawak’s main opposition party have grown over the past three state elections. It won one seat in 2001, followed by six in 2006. In 2011, it doubled its tally, winning 12 seats.
State chairman: Mohamad Fidzuan Zaidi
This election will be the maiden outing for the PAS splinter party, a member of the Pakatan Harapan opposition grouping along with PKR and DAP.
Parti Keadilan Rakyat (PKR)
State chairman: Baru Bian
PKR has yet to make an impact in Sarawak. In 2006, it contested 25 seats but won only one, though its fortunes improved in 2011 when it won three seats.
Parti Islam SeMalaysia (PAS)
State chairman: Jofri Jaraiee
PAS has yet to win a seat in Sarawak. Its best result so far has been in Beting Maro in 2011, where its candidate lost by a slim 391-vote majority to Barisan Nasional's Razaili Gapor of PBB.
Sarawak Workers Party (SWP)
The party has two assemblymen. On April 20, SWP founder Larry Sng quit as party president, leaving the leadership of the party in question.
State Reform Party Sarawak's (STAR)
The party did not contest the 2011 state polls, while its seven candidates in the 2013 general election fared badly. After the death of its permanent chairman Dr Patau Rubis on March 20, the party appointed Lina Soo as its new leader.
Parti Bansa Dayak Sarawak Baru (PBDS Baru)
President: Louis Jarau
PBDS Baru is an Opposition party set up after the demise of PBDS, a BN component party that was deregistered in 2004. The Registrar of Societies approved PBDS Baru in 2013.
Tan Sri Stephen Kalong Ningkan is appointed the first Chief Minister of Sarawak.
Datuk Seri Tawi Sli, from Sarawak Alliance (Pesaka), takes over as Chief Minister.
Tun Abdul Rahman Ya'kub takes office as Chief Minister and later becomes the fourth Governor of Sarawak.
Abdul Rahman’s nephew Tun Abdul Taib Mahmud, who was earlier appointed as State Minister for Land and Mines, succeeds his uncle as Chief Minister.
Sarawak Barisan under the leadership of Taib adopts the Barisan Plus formula to resolve the conflict between coalition component parties SNAP and its breakaway PBDS. Under the formula, both parties are allowed to use their own symbols to contest against each other, even though both are Barisan components, in disputed seats.
Abdul Rahman is removed as Governor, a move that sparks a political crisis in Sarawak.
Taib calls for snap elections, outmanouvering his rivals in the political crisis. Known as the Ming Court Affair, the crisis involves a dispute with Abdul Rahman.
Barisan’s second-biggest component party SUPP performs badly in urban seats, winning only six of the 19 seats contested.
After 33 years helming the state, Taib steps down as Chief Minister, with Tan Sri Adenan Satem succeeding him. Taib is appointed Sarawak Governor.
A split in Barisan component parties SUPP and SPDP gives rise to breakaway parties UPP and Teras, complicating seat allocation among parties for the coming polls.
