1988–2000: Creation and SDP contests Aljunied GRC was formed in
1988 and was won by the governing
People's Action Party (PAP) against the
Singapore Democratic Party (SDP) with 56.33% of the vote in a two-way contest. It was uncontested in
1991. The SDP returned to the GRC in
1997, but with a much poorer result compared to 1988, garnering 32.98% of the vote compared to the 43.67% they had previously garnered.
2001–2010: Entry of WP and 2006 general election Aljunied GRC was uncontested again in
2001; the WP had attempted to nominate a team for the GRC, however, it was disqualified. In
2006, the WP successfully nominated a team for the GRC, which lost with 43.91% of the vote. By virtue of the WP team's performance, the sole
non-constituency MP (NCMP) seat at the election was offered to one of their members;
Sylvia Lim accepted it.
2011–present: WP representation In 2011, party leader
Low Thia Khiang, who had left his seat at
Hougang Single Member Constituency (SMC), led a WP team in Aljunied GRC against the PAP team led by
George Yeo and
Lim Hwee Hua. With 54.72% of the vote, they won the first GRC for the opposition since the creation of GRCs in 1988.
2015: Vote recount and near-loss In
2015, a PAP team led by
Yeo Guat Kwang, then-MP for
Ang Mo Kio GRC and former MP for Aljunied GRC, contested Aljunied GRC. After the vote count was completed, said team requested a
recount as the initial difference in votes between the PAP and WP teams was under 2% of the vote. Following the recount, Aljunied GRC's electoral result was declared last at around 3.10am the morning after Election Day; the unchanged WP team retained it by 1.9% of the vote, or 2,612 votes.
2020: WP entrenchment In 2020, Low and
Chen Show Mao declined to run for re-election. Led by new party leader
Pritam Singh, the WP retained the GRC with 59.95% of the vote, a positive swing of 9% from the previous election.
2025 general election In August 2024, the PAP appointed Jagathishwaran Rajo and Kenny Sim to replace Chua Eng Leong and Alex Yeo respectively as the chairpersons of the Eunos and Paya Lebar PAP branches. The PAP again replaced three of its five branch chairpersons for Aljunied GRC in February 2025, appointing Faisal Abdul Aziz, Daniel Liu and Adrian Ang to replace Kenny Sim, Shamsul Kamar and
Victor Lye. On 11 March 2025, the
Elections Department (ELD)
updated the electoral divisions for the
general election later in the same year. Polling districts in Aljunied GRC to the east of Bedok Reservoir were absorbed by
Tampines GRC; the number of MPs for Aljunied GRC remained at five. This was the first time an opposition-held constituency had its boundaries redrawn. Prior to the same election, the WP announced 2 new candidates for the GRC:
Fadli Fawzi, former candidate for
Marine Parade GRC, and political newcomer
Kenneth Tiong. They were to contest alongside the incumbent MPs,
Pritam Singh,
Sylvia Lim and
Gerald Giam except
Faisal Manap.
Faisal Manap chose to contest in
Tampines GRC, a decision Singh later described as fulfilling a long-standing wish for Faisal. Despite a national swing towards the PAP, the WP retained the GRC with 59.71% of the vote, a vote share similar to that of 2020. ==Members of Parliament==
