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.
