During the 2006 general election, the GRC was considered a battleground as it faced its first electoral contest since its creation; all prior general elections had seen walkovers for the PAP. A group of Generation X candidates from the Workers' Party (WP), led by Yaw Shin Leong, was contesting against the PAP.[5] Lee, the PAP anchor and then-Prime Minister, called the WP team a "suicide squad"; the WP team responded by claiming that they were not pushovers.[6] The PAP won 66.14% of the vote.[7]
During the 2011 general election, despite a national swing against the PAP, the PAP team won an improved 69.33% of the vote against the Reform Party (RP).[7] At the same general election, the PAP lost Aljunied GRC to the WP.[8]
Before the 2020 general election, with the abolition-in-practice of six-member GRCs, the GRC was shrunk to five members, with the Yio Chu Kang division carved out to become Yio Chu Kang SMC.[14] Newcomers Ng Ling Ling and Nadia Ahmad Samdin joined the team while Koh, the MP for the Yio Chu Kang division, left for Tampines GRC.[15][16] The PAP defeated the RP with 71.91% of the vote.[7]
Prior to the 2025 general election, Jalan Kayu SMC was carved from Ang Mo Kio GRC.[17] During the election, the GRC saw its first three-way contest between the incumbent PAP, the People's Power Party (PPP), and the Singapore United Party (SUP), the last of which was participating in its first general election.[18] Lee, now the Senior Minister, continued to lead the PAP team, while Jasmin Lau, a newcomer, and Victor Lye, a former team leader for the PAP in Aljunied GRC, were fielded to replace Ng and Gan, who had retired from politics.[19][20][21] The PAP won the contest with almost 79% of the vote; the other two parties received around 10% each.[22] For failing to secure at least 12.5% of the vote, both PPP and SUP forfeited their election deposits.[22]
^ Balaji died in his sleep on 27 September 2010 due to cancer relapse. No by-election was held as his death did not fully vacate the parliamentary representation in the GRC.
