About Tan Cheng Bock
Adrian Tan Cheng Bock (born 26 April 1940) is a Singaporean former politician and physician who has served as the secretary-general of the Progress Singapore Party (PSP) between 2019 and 2021 and chairperson since 2021. A former member of the governing People's Action Party (PAP), he was the Member of Parliament (MP) for Ayer Rajah Single Member Constituency (SMC) between 1980 and 2006. He left politics before the 2006 general election and later left the PAP in 2011 to contest in the 2011 presidential election, losing marginally with 34.85% of the vote to Tony Tan in a four-cornered fight. In 2019, Tan founded the opposition Progress Singapore Party (PSP). The PSP did not win any seats in the 2020 or 2025 general elections; however, they were awarded two non-constituency MP seats in 2020 after their team for West Coast Group Representation Constituency (GRC), led by Tan himself, won 48.31% of the vote, the closest result in the general election. He announced his retirement from politics shortly after the 2025 general election, but has remained a PSP member.
