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. 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. Prior to that date, all constituencies were Single Member Constituencies (SMCs). Now, 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.
According to the Constitution and the PEA, there must be between three and six MPs in a GRC. The precise number of MPs in each GRC is declared by the President at the Cabinet's direction prior to a general election. For the purposes of the 2015 general election, there were 13 SMCs and 16 GRCs, and each GRC had between four and six MPs.
Critics disagree with the government's justifications for introducing the GRC scheme, noting that the proportion of minority MPs per GRC has decreased with the advent of five-member and six-member GRCs. By having teams of candidates standing for election for GRCs helmed by senior politicians, the ruling People's Action Party has also used GRCs as a means for bringing first-time candidates into Parliament. Moreover, the GRC scheme is also said to disadvantage opposition parties because it is more difficult for them to find enough candidates to contest GRCs. Furthermore, it is said that the GRC scheme means that electors have unequal voting power, weakens the relationship between electors and MPs, and entrenches racialism in Singapore politics.
