A group representation constituency (GRC) is a type of electoral division or constituency in Singapore in which teams of candidates, instead of individual candidates, compete to be elected into Parliament as the Members of Parliament (MPs) for the constituency. Synonymous to the party block voting (PBV) or the general ticket used in other countries, the Government stated that the GRC scheme was primarily implemented to enshrine minority representation in Parliament: at least one of the MPs in a GRC must be a member of the Malay, Indian or another minority community of Singapore. In addition, it was economical for town councils, which manage public housing estates, to handle larger constituencies.

The GRC scheme came into effect on 1 June 1988, and was first introduced at the general election that same year. Prior to that date, all constituencies were Single Member Constituencies (SMCs). The Parliamentary Elections Act (Cap. 218, 2008 Rev. Ed.) ("PEA") states that there must be at least eight SMCs, and the number of MPs to be returned by all GRCs cannot be less than a quarter of the total number of MPs. Within those parameters the total number of SMCs and GRCs in Singapore and their boundaries are not fixed but are decided by the Cabinet, taking into consideration the recommendations of the Electoral Boundaries Review Committee. Per the Constitution and the PEA, there must be between three and six MPs in a GRC. The number of MPs in each GRC is declared by the President at the Cabinet's direction before a general election. As of the latest 2025 general election, there were 15 SMCs, 8 four-member GRCs and 10 five-member GRCs, totalling 97 MPs.

Reception towards to the GRC system is mixed, with some critics disagreeing with the government's justifications for introducing the scheme, noting that the proportion of minority MPs per GRC has rather decreased with the advent of five-member and six-member GRCs, though process of reducing its average size of GRCs were gradually reduced in subsequent elections in favour of SMCs. In addition, the ruling People's Action Party (PAP) has been described as using GRCs as a means of bringing in politically inexperienced candidates into Parliament by "riding on the coattails" of GRCs helmed by senior politicians, particularly Cabinet members who are deployed to each incumbent PAP-held GRC, as "anchor ministers". Moreover, the GRC scheme is also noted to particularly disadvantage opposition parties, by raising the threshold to find sufficient candidates with the political expertise and capability to contest GRCs. Furthermore, it is said that the GRC scheme means that electors may have unequal voting power, weakens the relationship between electors and MPs, and entrenches racialism in Singapore politics due to its emphasis on minority representation.

History There are two types of electoral division or constituencyConstitution, Art. 39(3): "In this Article and in Articles 39A and 47, a constituency shall be construed as an electoral division for the purposes of Parliamentary elections." in Singapore: the single member constituency (SMC) and the group representation constituency (GRC). In a GRC, a number of candidates comes together to stand for elections to Parliament as a group. Each voter of a GRC casts a ballot for a team of candidates, and not for individual candidates. The GRC scheme was brought into existence on 1 June 1988 by the Constitution of the Republic of Singapore (Amendment) Act 1988. The Constitution of the Republic of Singapore (Amendment) Bill (No. B 24 of 1987) was read in Parliament for the first time on 30 November 1987. The Second Reading took place on 12 January 1988, and it was referred to a select committee which presented its report on 5 May 1988. The bill was read for the third time and passed on 18 May 1988. It came into force on 31 May 1988. and the Parliamentary Elections (Amendment) Act 1988.. The Parliamentary Elections (Amendment) Bill (No. B 23 of 1987) had its First and Second Readings on 30 November 1987 and 11–12 February 1988 respectively. Like the Constitution of the Republic of Singapore (Amendment) Bill, it was committed to a select committee which rendered its report on 5 May 1988. The bill was read for a third time and passed on 18 May 1988 and came into force on 1 June 1988, a day after the 1988 Act amending the Constitution commenced.

The original stated purpose of GRCs was to guarantee a minimum representation of minorities in Parliament and ensure that there would always be a multiracial Parliament instead of one made up of a single race. Speaking in Parliament during the debate on whether GRCs should be introduced, First Deputy Prime Minister and Minister for Defence Goh Chok Tong said he had first discussed the necessity of ensuring the multiracial nature of Parliament with Prime Minister Lee Kuan Yew in July 1982. Then, Lee had expressed concern about the voting patterns of younger Singaporeans, who appeared to be apathetic to the need of having a racially balanced slate of candidates. He was also worried about more Singaporeans voting along racial lines, which would lead to a lack of minority representation in Parliament..

Lee had also proposed to twin constituencies and have Members of Parliament (MPs) contest as a pair, one of whom had to be from a minority community. However, Malay MPs were upset that this implied they were not electable on their own merits. Feeling that the twinning of constituencies would lead to Malay MPs losing confidence and self-respect, the Government dropped the proposal.Goh, Parliamentary Elections (Amendment) Bill, cols. 180–183; .

Therefore, the Government felt that the best way to ensure minority representation in Parliament was to introduce the GRC scheme. In addition, it took the view that such a scheme would complement the introduction of town councils to manage public housing estates, as it would be economical for a town council to manage a group of three constituencies.Goh, Parliamentary Elections (Amendment) Bill, cols. 183–184. Subsequently, in 1991, the Government said that GRCs also minimized the need to redraw the boundaries of constituencies which had grown too big for the MPs serving them, and, in 1996, GRCs were said to provide Community Development Councils with the critical mass of residents that they needed to be effective..

Three proposals for minority representation in Parliament had been considered by a 1966 Constitutional Commission chaired by the Chief Justice Wee Chong Jin. The first was to have a committee of representatives of minorities that would elect three persons from amongst its members to represent minorities in Parliament., para. 46(1). However, this was rejected as the Commission felt that it would be an inappropriate and retrogressive move in that unelected members should not be allowed to dilute the elected chamber.Constitutional Commission, 1966, para. 47. The second proposal, which was to have proportional representation,Constitutional Commission, 1966, para. 46(2). was also rejected on the grounds that it would intensify party politics along racial lines and eventually "perpetuate and accentuate racial differences". This would then make it increasingly difficult, if not impossible, to achieve a single homogeneous community out of the many races that form the population of the Republic.Constitutional Commission, 1966, para. 48. The third proposal was to have an upper house in Parliament composed of members elected or nominated to represent the racial, linguistic and religious minorities in Singapore.Constitutional Commission, 1966, para. 46(3). This proposal was also scrapped because of backward-looking since politicians should attain a seat in Parliament through taking part in elections.Constitutional Commission, 1966, para. 49.

In 1988, 39 SMCs were grouped into 13 three-member GRCs, making up 39 out of a total of 81 elected seats in Parliament. The Constitution and the Parliamentary Elections Act were changed in 1991; . and again in 1996; . to increase the maximum number of MPs in each GRC from three to four, and then to six. The 2001 and 2006 elections had only nine SMCs and 14 GRCs of five or six MPs, with a peak staggering at 5.36 MPs; it also marked the first time where at least two existing GRCs have its electoral boundaries being intact from the last general election, with each subsequent election saw between two and five GRCs being untouched.Parliamentary Elections (Declaration of Group Representation Constituencies) Order 2006 (S 146/2006); .

On 27 May 2009, the Government announced that it would refine the size and number of GRCs. This could be achieved without amending either the Constitution or the Parliamentary Elections Act. Instead, when the next EBRC was appointed, its terms of reference would instruct the Committee to plan for fewer six-member GRCs than at present, and to reduce the average size of each GRC. The new configuration have to abide to the clause of not exceeding an average of five MPs with more than 12 SMCs, to account for the adaptability of increased electorate, and improve rationale on connecting between voters and MPs. In the 2011 general election, SMCs returned to Parliament 12 MPs and 15 GRCs a total of 75 MPs.. Thereafter, the average size of GRCs was gradually reduced and the number of SMC was increased, which result in the removal of six-member GRCs beginning in 2020.

In 2023, Progress Singapore Party's (PSP) non-constituency Member of Parliament (NCMP), Hazel Poa, raised a private member's motion to abolish GRC, citing outcomes where candidates ride on the coattails of more established teammates, reduced voters' choice over election results. During the parliament debate, Poa mentioned vacancies in the GRC when MPs resign from their seat midterm, citing Halimah Yacob's resignation in 2017 to contest in the 2017 Singaporean presidential election and Tharman Shanmugaratnam's upcoming resignation to contest in the 2023 Singaporean presidential election. Chan Chun Sing, Minister-in-charge of the Public Service, in response to Poa, said WP and PSP also relied on the "star power" of Low Thia Khiang and Tan Cheng Bock to win Aljunied GRC in 2011 and PSP having NCMPs now in parliament. Leader of the Opposition and Workers' Party's (WP) chief Pritam Singh also highlighted the usage of GRC for gerrymandering, citing the merging of SMCs, in close contest between PAP and WP, into GRC in the next election. WP also called for the abolition of GRCs. Senior Minister Teo Chee Hean responded that accusations of gerrymandering existed long ago and asked Singh to suggest to EBRC to break up opposition held GRCs into SMCs. However, these motions were ultimately rejected by Parliament.
