Creation From its creation until the
2006 general elections, the GRC was always uncontested. In the 2006 general elections, the
Singapore Democratic Party led by
Chee Soon Juan's sister Chee Siok Chin contested in the GRC against the PAP team led by
Khaw Boon Wan in which the PAP team won with 76.7% against the SDP's 23.3%. In the
2011 general election, the PAP won against the SDP team led by former Workers' Party Aljunied GRC candidate
James Gomez with a reduced majority of 63.9%. In the
2015 general elections, although the SDP did not contest in the GRC, the National Solidarity Party contested and the PAP won against the NSP with 72.3% of the vote. Prior to the
2020 general election, Khaw and Lim Wee Kiak retired,
Amrin Amin moved to contest in
Sengkang GRC unsuccessfully and
Ong Ye Kung became the anchor minister for the PAP Sembawang GRC team. The PAP team proceeded to win with 67.3% of the vote.
2025 general election For the
2025 general election, the majority of the residential area of Sembawang West ward was carved out of the GRC to form a new
Sembawang West Single Member Constituency (SMC) in order to reduce the number of voters in the GRC. In the same year, the
National Solidarity Party (NSP) and the
Singapore Democratic Party (SDP) entered talks hoping to avert a three-cornered fight in the GRC. However, on 12 April, both parties were unable to come to an agreement as NSP rejected SDP's proposal for NSP to instead contest in Holland–Bukit Timah. Due to the creation of Sembawang West SMC, Poh Li San, left the GRC team to stand for reelection alone. A reconfigured PAP team defeated SDP with 67.75% of the vote to the SDP's 29.93%, while the NSP lost their deposit with 2.32% of the vote. ==Members of Parliament==
