2015 Singaporean general election

General elections were held in Singapore on 11 September 2015 to elect members of Parliament. They were the fourteenth general elections since the introduction of self-government in 1959 and the twelfth since independence in 1965. President Tony Tan dissolved parliament on 25 August on the advice of Prime Minister Lee Hsien Loong three weeks before the election. The number of elected seats was increased from 87 to 89 from the previous election. This was the third election contested by Lee as prime minister.

The elections were held a few months after the death of Lee Kuan Yew in March, who was a founding father of the country and a key figure in its development as a nation. His passing was widely seen as strengthening public support for the governing People's Action Party (PAP) as the national mood of remembrance and unity grew. The government also focused heavily on SG50 celebrations, which marked Singapore's golden jubilee of independence and stirred strong feelings of patriotism. The election was called earlier than expected, several months before the anticipated 2016 timeline. As a result, the 12th Parliament (2011–2015) ended sooner than usual, making it the shortest term since the 7th Parliament (1989–1991).

For the third consecutive election, the PAP did not return to government on nomination day. In addition, all constituencies were contested, marking a first in Singapore's post-independence history where there were no walkovers for the PAP. Nevertheless, the PAP achieved a landslide victory in the election, retaining its supermajority and increasing its popular vote share by almost 10 percentage points to 69.86%, its best result since 2001. The party won 83 seats while the opposition Workers' Party (WP) won six, retaining Aljunied Group Representation Constituency (GRC) and Hougang Single Member Constituency (SMC) with reduced majorities. The WP's overall vote share fell by about 7% across the 28 seats it contested. Three non-constituency seats (NCMPs) were also allocated to the WP, resulting in the 13th Parliament being the first in which only two political parties were represented, whether through elected MPs or NCMPs.
