Gabungan Parti Sarawak (GPS)

Sarawak's governing coalition, formed on 12 June 2018 by four parties that quit Barisan Nasional after GE14, registered as a coalition in November 2018, and part of the federal unity government since December 2022.

Party membership of a coalition changes over time. The dates behind this are the same ones the Coalition River on the home page is drawn from.

The account

Gabungan Parti Sarawak is the coalition that governs Sarawak. It exists because of what happened in May 2018. Barisan Nasional lost the federal government for the first time since independence, and on 12 June 2018 the four parties that ran Sarawak inside BN — PBB, SUPP, PRS and PDP — announced that they were leaving it and forming a coalition of their own. Every one of the four is a Sarawak party, and GPS contests only Sarawak seats.

The break was not just a change of name. GPS applied to the Registrar of Societies in early July 2018, and on 19 November 2018 the Home Minister told Parliament the registration had been approved. That matters more than it sounds: a registered coalition is a political association in its own right, with its own logo on the ballot, rather than a private understanding between parties that can be denied later.

GPS unveiled its logo on 9 January 2019 and launched formally in Kuching ten days after that, under the tagline "Sarawak First". Abang Johari Openg, who leads PBB, chairs it.

For a first-time voter the most useful thing to know about GPS is that it sits outside the peninsular contest between Pakatan Harapan and Perikatan Nasional, and has repeatedly chosen between them:

  1. February 2020it backed Muhyiddin Yassin for Prime Minister while stating plainly that it was not a Perikatan Nasional component, only "friendly" to it.
  2. 20 November 2022it pledged support for Perikatan first, then four days later said the choice of Prime Minister was for the Yang di-Pertuan Agong; Anwar Ibrahim was sworn in that day, and GPS became one of the coalitions in his unity government.
  3. 3 December 2022Fadillah Yusof of PBB became a Deputy Prime Minister, the first from Sarawak.
  4. 16 December 2022it signed the written cooperation agreement between the unity government's coalitions.

In Sarawak itself the coalition's position is close to unchallenged. At the December 2021 state election GPS took 76 of 82 seats on roughly 61 per cent of the vote, with turnout at 60.67 per cent. By April 2026 it held 79 of the 82, after by-elections and defections: PBB 47, SUPP 13, PRS 11 and PDP 8. Two months after that election the state constitution was amended to rename the Chief Minister as Premier, a title Abang Johari took on 1 March 2022.

Why the margins are so wide is where accounts diverge, and each belongs to whoever makes it. Arnold Puyok of Universiti Malaysia Sarawak points to development spending and the "Sarawak First" pitch bringing Dayak voters back. James Chin and other analysts quoted before the 2021 poll emphasised that the opposition vote was split four ways. PRS's James Masing, at the coalition's own launch, accepted the critics' description of GPS as "old wine in a new bottle" as fair about its leaders, while arguing the bottle was genuinely new.

The next test is close. Sarawak's assembly term expires in February 2027 unless dissolved earlier, and an election must follow within 60 days of dissolution — by April 2027 at the latest. A 2025 Ordinance raised the statutory number of elected seats from 82 to 99, but the new constituencies still need to be drawn and approved, and Abang Johari said in April 2026 that the election might yet be fought on the old 82. He also said GPS would field candidates in every seat.

What the sources say

How it was formed

Four parties then governing Sarawak — Parti Pesaka Bumiputera Bersatu (PBB), Sarawak United People's Party (SUPP), Parti Rakyat Sarawak (PRS) and the Progressive Democratic Party (PDP) — announced on 12 June 2018 that they were withdrawing from Barisan Nasional to form Gabungan Parti Sarawak, weeks after the May 2018 general election.

The Borneo Post

The application to register the coalition was submitted in early July 2018. GPS pro tem secretary-general Alexander Nanta Linggi said the parties had been told the process would take three to six months.

The Borneo Post

Home Minister Muhyiddin Yassin told the Dewan Rakyat, in his winding-up speech for Budget 2019 on 19 November 2018, that the registration had been approved and that the Registrar of Societies would issue the letter within days.

The Borneo Post

GPS appears on the Election Commission's published list of registered political parties, alongside Barisan Nasional, Pakatan Harapan, Perikatan Nasional and Gabungan Rakyat Sabah. It is therefore a registered political association in its own right, not only an understanding between four parties.

Suruhanjaya Pilihan Raya

The coalition unveiled its logo on 9 January 2019 and was formally launched at the State Indoor Stadium in Petra Jaya, Kuching, on 19 January 2019, two months after the registration was approved. Chief Minister Abang Johari Openg, who is also PBB president, is its chairman.

At the launch Abang Johari set out nine stated pillars for the coalition, among them upholding the constitution, safeguarding Sarawak's rights and interests, and strengthening the state's economy. GPS campaigns under the tagline "Sarawak First".

Membership

GPS has had the same four component parties since it was formed: PBB, SUPP, PRS and PDP. All four are Sarawak-based, and GPS contests only in Sarawak.

PRS deputy president James Masing said at the launch that critics had called GPS "old wine in a new bottle" and that the description was fair as to its leaders' long experience, while arguing the coalition itself was new.

Elections and federal role

At the end of 2019 GPS held 18 seats in the Dewan Rakyat and 68 of the 82 seats in the Sarawak state assembly.

The Borneo Post

February 2020

In February 2020, during the change of federal government, GPS backed Muhyiddin Yassin for Prime Minister but stated it was not a component of Perikatan Nasional. A GPS statement said that "at this juncture, GPS will only be a political party that is friendly to the Perikatan Nasional."

Where things stand

As of April 2026, GPS held 79 of the 82 seats in the Sarawak assembly: PBB 47, SUPP 13, PRS 11 and PDP 8.

Free Malaysia Today

The assembly's term expires in February 2027 unless it is dissolved earlier, and an election must follow within 60 days of dissolution, so a Sarawak state election is due by April 2027 at the latest. Abang Johari said in April 2026 that GPS would contest every seat.

Free Malaysia Today

The Sarawak assembly passed a Bill in July 2025 to raise the number of elected seats from 82 to 99, and the Dewan Undangan Negeri (Composition of Membership) Ordinance 2025 commenced on 8 August 2025; the new constituencies still require the federal and Election Commission processes to draw them. Abang Johari said in April 2026 that the election might still be fought on 82 seats if redelineation was not completed in time.

Where accounts differ

The exact date on which the registration certificate was issued is not settled in the sources opened. The Home Minister said on 19 November 2018 that approval had been given and the letter would follow "in a day or two"; the Borneo Post's year-end review dates the launch as "two months after its registration was approved by the Home Ministry" without giving the certificate date. A 22 November 2018 date circulates in secondary summaries and could not be confirmed against a primary or contemporaneous report.

The Borneo PostThe Borneo Post

How much of GPS's dominance rests on its own appeal is disputed among researchers. Arnold Puyok of Universiti Malaysia Sarawak attributes the Dayak swing back to GPS to development spending and its "Sarawak First" positioning; James Chin and other analysts quoted before the 2021 polls emphasised instead that the opposition vote was split between DAP, PKR, Amanah and PSB.

Arnold PuyokMalaysiakini

Abang Johari has framed GPS's federal dealings as a partnership conditional on respect for the Malaysia Agreement 1963 and Sarawak's constitutional position, saying in April 2026 that outside parties should "not interfere with the Sarawak family." That is the coalition's own characterisation of the relationship, not a settled description of it.

Common questions

Which parties are in Gabungan Parti Sarawak?

Four: Parti Pesaka Bumiputera Bersatu (PBB), the Sarawak United People's Party (SUPP), Parti Rakyat Sarawak (PRS) and the Progressive Democratic Party (PDP). They are the same four that left Barisan Nasional on 12 June 2018 to form the coalition, and all four are Sarawak-based. GPS contests only Sarawak seats.

The Borneo PostFree Malaysia Today

It is registered. GPS applied to the Registrar of Societies in early July 2018, and the Home Minister told the Dewan Rakyat on 19 November 2018 that the registration had been approved. The Election Commission lists GPS among Malaysia's registered political parties and coalitions.

The Borneo PostSuruhanjaya Pilihan Raya

Why did GPS leave Barisan Nasional?

The four Sarawak parties announced their withdrawal on 12 June 2018, weeks after Barisan Nasional lost the May 2018 general election, and set up a coalition made only of Sarawak-based parties. At the 2019 launch, Abang Johari set out nine pillars including safeguarding Sarawak's rights and interests, and the coalition adopted the tagline "Sarawak First".

The Borneo PostThe Borneo Post

Is GPS part of the federal government?

Yes. GPS won 23 parliamentary seats in November 2022, and after initially pledging support to Perikatan Nasional on 20 November it said on 24 November that the appointment of the Prime Minister was for the Yang di-Pertuan Agong. It became one of the coalitions in Anwar Ibrahim's unity government and signed the coalitions' cooperation agreement on 16 December 2022.

When is the next Sarawak state election?

The state assembly's term expires in February 2027 unless it is dissolved earlier, and an election must be held within 60 days of dissolution, so by April 2027 at the latest. Whether it is fought on 82 seats or the 99 provided for by a 2025 Ordinance depends on whether the new constituencies are drawn and approved in time.
