A by-election in the Single Member Constituency of Bukit Batok, which has about 25,000 eligible voters, is needed following the resignation of the People's Action Party (PAP) MP David Ong on March 14.
The PAP has ruled Singapore since 1959, when it was still a British colony. Its rule has relied on a combination of independent Singapore’s affluence in comparison with its neighbours and political repression.
Ong won 72% of the vote in the September’s general elections, defeating the Singapore Democratic Party’s (SDP) Sadasivam Veriyah (26.4%) and independent Samir Salim Neji (0.6%).
