Hougang Single Member Constituency

The constituency was first formed prior to the 1988 general election and was won by the People's Action Party (PAP) in its debut.

However, PAP's representation of Hougang SMC would only last three years, when it lost the seat to the Worker's Party (WP) candidate Low Thia Khiang after an almost 12% swing during the 1991 general election.

In the 2006 general election, Senior Minister Goh Chok Tong was tasked to help the PAP win back the two opposition wards of Hougang SMC and Potong Pasir SMC with a $100 million plan to upgrade the constituency.[1][2] However, Low retained the seat with 62.7% of the votes.[2]

From 1991 to 2011, it was one of only two opposition-held (i.e. non-PAP) seats in Parliament.

During the 2011 general election, Low Thia Kiang left to contest the nearby Aljunied GRC , Yaw Shin Leong, who retained the seat with 65% of the vote.

On 15 February 2012, Yaw was expelled from the party for personal indiscretions, triggering a by-election.[3] Png Eng Huat retained the seat for the party with 62.1% of the vote.[4]

Png retired prior to the 2020 general election; the WP candidate Dennis Tan Lip Fong retained the seat in that election with 61.2% of the vote.[5]

The seat is located in the North-East Region of the country, with the closest train station being the namesake Hougang MRT station on the North East Line and the Cross Island Line (currently under construction), although the station itself is not located within the SMC but just outside it, in the adjacent Aljunied GRC – which is also represented by WP MPs. Hougang Community Club and Hougang Neighbourhood Park are located within the constituency.

The constituency is almost entirely an enclave within Aljunied GRC, except for Hougang ActiveSG Sports Centre which consists of Hougang Stadium, a sports hall and swimming pool that comes under Ang Mo Kio GRC on Hougang SMC's western border.[6] The constituency has been labeled a stronghold for the WP by political analysts, having been retained by the party since 1991.[5]

Note: The Elections Department Singapore (ELD) does not include rejected votes for calculation of candidate's vote share. Hence, the total of all candidates' vote share will be 100%.
