SINGAPORE - The People's Action Party (PAP) has won all but one of the 13 single-member constituencies (SMC) at the 2015 General Election, including wresting back the Punggol East SMC from the Workers' Party (WP).

The WP retained its seat in Hougang SMC, with Mr Png Eng Huat taking 57.7 per cent of vote over PAP new face Lee Hong Chuang (42.3 per cent).

But the WP's Ms Lee Li Lian lost her seat in Punggol East. PAP veteran Charles Chong took 51.8 per cent of the votes cast, beating Ms Lee's 48.2 per cent. The Punggol East seat is the PAP's closest win for SMCs.

Radin Mas SMC, which saw a three-cornered fight between the PAP's Mr Sam Tan, Reform Party's Mr Kumar Appavoo and independent candidate Han Hui Hui, was the PAP's best-performing single-seat ward.

Mr Tan took 77.3 per cent of votes, beating Mr Appavoo's 12.7 per cent and Ms Han's 10 per cent. Ms Han will lose her election deposit for garnering less than 12.5 per cent of the total votes in the constituency.

The PAP also won Fengshan SMC, one of the most hotly contested seats of the 2015 General Election. New face Cheryl Chan, who is taking over the helm from retiring MP Raymond Lim, won with 57.5 per cent of votes, beating the WP's Mr Dennis Tan (42.5 per cent).

The two other three-cornered fights also went to the PAP.

Bukit Batok was won by Mr David Ong, who garnered 73 per cent of votes. He beat the Singapore Democratic Party's Sadasivam Veriyah (26.4 per cent). Independent candidate Samir Salim Neji took just 0.6 per cent of votes and will also lose his election deposit.

MacPherson SMC was won by the PAP's Ms Tin Pei Ling. She got 65.6 per cent of the votes cast, beating the WP's Bernard Chen (33.6 per cent) and the National Solidarity Party's Mr Cheo Chai Chen, who took 0.8 per cent of the vote. Mr Cheo also loses his election deposit.
