Parliamentary elections in Singapore

Parliamentary elections in Singapore must be held within three months after five years have elapsed from the date of the first sitting of a particular Parliament of Singapore. However, in most cases Parliament is dissolved and a general election called at the behest of the Prime Minister before the five-year period elapses. The number of constituencies or electoral divisions is not permanently fixed by law, but is declared by the Prime Minister prior to each general election pursuant to the , which governs the conduct of elections to Parliament, taking into account recommendations of the Electoral Boundaries Review Committee. For the 2015 general election, there were 89 seats in Parliament organised into 13 Single Member Constituencies (SMCs) and 16 Group Representation Constituencies (GRCs). Each SMC returns one Member of Parliament while each GRC returns between three and six MPs, at least one of whom must be from the Malay, Indian or other minority communities. A group of persons wishing to stand for election in a GRC must all be members of the same political party, or a group of independent candidates. The voting age in Singapore is 21 years.
