The Radin Mas Single Member Constituency is a single-member constituency (SMC) in central Singapore. It is managed by Tanjong Pagar Town Council. ^[1] The current Member of Parliament (MP) for the constituency is Melvin Yong from the governing People's Action Party (PAP).

History

Radin Mas Constituency was created in 1976; Govindasamy Naidu from the PAP won 75.65% of the vote. ^[2] Bernard Chen retained the constituency in one of two by-elections in 1977 after Naidu died. ^[3] The PAP would continue to retain the constituency in the 1980 and 1984 general elections. ^{[4] [5]}

In 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. ^[6]

For the 2011 general election, Radin Mas Single Member Constituency was carved from Tanjong Pagar GRC, where it had previously been a division. ^{[7] [a]} Sam Tan, the incumbent PAP MP for the Radin Mas division, won the SMC with 67.1% of the vote against Yip Yew Weng from the National Solidarity Party (NSP). ^{[7] [9]}

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. ^{[10] [11]}

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; ^[12] he won 74.01% of the vote against Kumar Appavoo from the Reform Party (RP), who had been contesting the SMC since 2015. ^{[13] [14]}

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. ^[15] He won 23.52% of the vote, while Appavoo, now under the banner of the coalition People's Alliance for Reform (PAR), lost his $13,500 deposit with 7.36% of the vote. Yong won reelection with 69.12% of the vote. ^{[14] [16]}
