First existence (1976–1988)
Radin Mas Constituency was created prior to the 1976 general election; [2] PAP candidate Govindasamy Naidu defeated Othman bin Abdullah from the Workers' Party (WP) with 75.65% of the vote. [3]
In 1977, a by-election was called after Naidu died in office. [4] Bernard Chen retained the constituency for the PAP, defeating J. B. Jeyaretnam, the secretary-general of the WP, with 70.59% of the vote. [4] [5] Syed Abu Bakar Alsagoff, an independent, had also attempted to contest the by-election; however, he was disqualified after the end of nominations for being absent from the official register of electors, having not voted during the 1976 general election. [4]
During the 1980 and 1984 general elections, two different PAP candidates retained the constituency against WP candidate Wong Hong Toy, respectively obtaining 64.07% and 53.78% of the vote. [6] [7]
Prior to the 1988 general election, with the creation of group representation constituencies (GRCs), Radin Mas Constituency was abolished and made part of the three-member Tiong Bahru GRC. [8]
Second existence (2011–present)
For the 2011 general election, Radin Mas Single Member Constituency was carved from Tanjong Pagar GRC, which it had previously belonged to as a division. [9] [a] Sam Tan, the incumbent PAP MP for the division, stood for reelection, defeating Yip Yew Weng from the National Solidarity Party (NSP) with 67.1% of the vote. [9] [11]
In the 2015 general election, blogger Han Hui Hui ran as an independent candidate for the constituency. She won 10.03% of the vote, losing her election deposit of S$14,500 in the process for not winning at least 12.5% of the vote. Tan, on the other hand, retained the SMC with an improved 77.25% of the vote in a three-cornered fight. [12] [13]
Prior to the 2020 general election, Tan retired from politics. Melvin Yong, the incumbent MP for the Moulmein–Cairnhill division in Tanjong Pagar GRC, was fielded by the PAP to retain the SMC; [14] he garnered 74.01% of the vote, defeating Kumar Appavoo, candidate for the Reform Party (RP), who had been contesting the SMC since 2015. [15] [16]
In the 2025 general election, another three-cornered fight occurred in Radin Mas SMC after Darryl Lo, an independent candidate, ran in the constituency, claiming that there was no "credible opposition" in the constituency. [17] He won 23.52% of the vote, while Appavoo, now under the banner of the People's Alliance for Reform (PAR), a political coalition, lost his $13,500 deposit with 7.36% of the vote. Yong won reelection with 69.12% of the vote. [16] [18]
