History

Radin Mas Constituency was created in 1976, with Govindasamy Naidu from the PAP winning with 75.65% of the vote.^[1] Bernard Chen retained the constituency in one of two by-elections in 1977 after Naidu died.^[2] The PAP would continue to retain the constituency in the 1980 and 1984 general elections until 1988, when, with the creation of group representation constituencies (GRCs), it was abolished and made part of the three-member Tiong Bahru GRC.^[3]^[4]^[5]

For the 2011 general election, Radin Mas Single Member Constituency was created from Tanjong Pagar GRC, which replaced Tiong Bahru GRC upon the latter's abolition in 1991. Sam Tan from the PAP won with 67.1% of the vote against Yip Yew Weng from the National Solidarity Party (NSP).^[6]

In the 2015 general election, blogger Han Hui Hui ran as an independent candidate for the constituency. She won 10% of the vote, losing her election deposit of $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.^[7]

In the 2025 general election, Darryl Lo, another independent candidate, ran in the constituency, claiming that there was no "credible opposition" in Parliament.^[8] He won 23.47% of the local vote, while candidate-since-2015 Kumar Appavoo from the Reform Party (RP), a constituent party of the People's Alliance for Reform (PAR), lost his $13,500 deposit with 7.36% of the vote. Melvin Yong, the incumbent MP for the SMC, won for the PAP with 69.17% of the vote, a worse result than the 74.01% he had won in 2020.^[9]
