Electoral history

Bukit Panjang Constituency was established for the 1955 general election. Goh Tong Liang from the Progressive Party (PP) defeated Lim Wee Toh from the Labour Front (LF).^[2]

In the subsequent 1959 general election, Lee Khoon Choy from the PAP won 58.31% of the vote in a four-way contest involving the Liberal Socialist Party (LSP), the Singapore People's Alliance (SPA) and the Malayan Indian Congress (MIC).^[3] The PAP, however, lost the seat in the 1963 general election to Barisan Sosialis (BS), founded by the former left-wing faction of the PAP. Ong Lian Teng, father of future PAP minister Ong Ye Kung, was elected.^[4] The PAP regained the seat in a walkover at one of five 1967 by-elections after all BS MPs resigned as part of a boycott, protesting the legitimacy of the government following Singapore's independence.^[5]

Following the by-election, the PAP continued to hold the constituency, with P. Selvadurai serving as its MP until the 1972 general election. He was then fielded in Kuo Chuan Constituency and succeeded by Lee Yiok Seng in Bukit Panjang. In that election, Lee won with 67.65% of the vote, defeating Workers' Party (WP) candidate Tang Song Khiang and United National Front (UNF) candidate Leyu Tan Jib, who secured 24.82% and 7.53% respectively.

At the 1988 general election, with the introduction of Group Representation Constituencies (GRCs), the seat was formally designated as Bukit Panjang Single Member Constituency.^[6]

Lee continued to serve as MP until the constituency was abolished and merged into Sembawang GRC in the 1991 general election.

Since 2006

From 1991 to 2006, Bukit Panjang SMC did not exist. It was reinstated during the electoral boundary review ahead of the 2006 general election. The reconstituted seat was formed from parts of the former Holland–Bukit Panjang GRC, which had absorbed the area in the 2001 general election.^[7] At the same time, Holland–Bukit Panjang GRC was dissolved in favour of Holland–Bukit Timah GRC.

Ahead of the 2020 general election, incumbent PAP MP Teo Ho Pin announced his retirement from politics.^[8] The PAP nominated Liang Eng Hwa, then-MP for the Zhenghua division of Holland–Bukit Timah GRC. The Singapore Democratic Party (SDP) contested the seat with infectious diseases expert Paul Tambyah as its candidate. Liang won with 53.74% of the vote, defeating Tambyah by 2,509 votes.^[9]

In March 2025, it was confirmed that both candidates would stand again in the 2025 general election.^[10] Liang was re-elected with an increased vote share of 61.41%, in line with a broader national swing towards the PAP.^[11][12]
