There are two types of electoral division or constituency 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 and the Parliamentary Elections (Amendment) Act 1988.
