2012 Hougang by-election

A parliamentary by-election was held in the Hougang Single Member Constituency (SMC) in Singapore on 26 May 2012. It was held to replace the vacant seat after incumbent Member of Parliament (MP) Yaw Shin Leong was expelled from the Workers' Party (WP) following revelations of his extramarital affairs. This marked the first by-election in almost two decades since 1992 at the Marine Parade Group Representation Constituency (GRC).

On polling day, the WP fielded Png Eng Huat, who won with 62.08% of the vote and defeated People's Action Party (PAP) candidate Desmond Choo, who received 37.92%. With this result, the WP successfully retained its long-held Hougang seat in Parliament, albeit with an slight negative swing of almost 3%. It was Singapore's first by-election of the 21st century.
