Constituencies in Singapore are electoral divisions which may be represented by single or multiple seats in the Parliament of Singapore. Constituencies are classified as either single member (SMC) or group representation constituencies (GRC). SMCs are single-seat constituencies but GRCs have several seats.
Boundaries of Electoral Constituencies
The boundaries of electoral constituencies in Singapore are decided by the Elections Department, which is under the control of the Prime Minister's Office. Electoral boundaries are generally announced close to elections, usually a few days before the election itself is announced. The have been accusations of gerrymandering regarding the redrawing of electoral boundaries and the dissolving of constituencies that return a high percentage of votes for parties other than the ruling PAP.
One of the cases that is often cited as evidence for gerrymandering is the case of the Cheng San Group Representation Constituency (GRC). In the 1997 Singaporean general election, the Cheng San GRC was contested by the PAP and the Workers' Party of Singapore (WP). The final result was very close, with the PAP winning by 53,553 votes to the WP's 44, 132 votes. By the time of 2001 general election the Cheng San GRC had been dissolved.
