Bukit Batok Single Member Constituency was a single member constituency (SMC) in the western area of Singapore. At abolition, it was managed by Jurong–Clementi Town Council.
History
[edit]Bukit Batok Constituency was created in 1972 from parts of the constituencies of Bukit Timah, Chua Chu Kang and Bukit Panjang. It was renamed Bukit Batok Single Member Constituency in 1988 after the creation of group representation constituencies (GRCs) and lasted until the 1997 general election.[1]
In 2016, the then-incumbent Member of Parliament (MP), David Ong from the governing People's Action Party (PAP), resigned after having an extramarital affair; a by-election was called to replace the empty seat.[2] On 7 May, Murali Pillai from the PAP defeated Singapore Democratic Party (SDP) secretary-general, Chee Soon Juan with a vote count of 61.2% to 38.8%.[3]
On 11 March 2025, the Elections Department Singapore updated the electoral divisions for the 2025 general election. Bukit Batok SMC was merged into Jurong East–Bukit Batok GRC.[4]
