General elections were held in Singapore on 7 May 2011. President S. R. Nathan dissolved parliament on 19 April 2011 on the advice of Prime Minister Lee Hsien Loong. Voting is mandatory in Singapore and is based on the first-past-the-post system. Elections are conducted by the Elections Department, which is under the jurisdiction of the Prime Minister's Office. Nomination day was held on 27 April 2011, and for the second election in a row, the PAP did not return to government on nomination day, but it did return to government on polling day. This election also marked the first and the only three-cornered fight since 2001 in Punggol East SMC.
The elections were described as a "watershed" by various parties. The ruling PAP reminded voters that the election will determine "Singapore's next generation of leaders". The Workers' Party called it a "watershed election" both for Singapore and the opposition, as it marked the first time in two decades that the only two incumbent opposition MPs moved out of their respective strongholds and contested in Group Representation Constituencies (GRCs), risking a situation where there would be "no elected opposition MPs". This was despite the elections having the highest proportion of contested seats since independence, with 82 of 87 seats contested. 2011 was the year that saw the highest proportion of seats contested since post-independence; with the second being in 1972 when 57 of 65 seats were contested, It marked the first electoral contests in Bishan–Toa Payoh (since 1991) and Holland–Bukit Timah, and also marked Tanjong Pagar as the only constituency to remain uncontested since its formation in 1991. This was the last general election to date where there were walkovers in at least one constituency as subsequent elections would see all constituencies being contested for the first time in post-independence since 1963.
The final results saw a six percentage point swing against the PAP from the 2006 elections to 60%, its lowest since independence. The results saw the ruling PAP winning 81 elected seats with the Worker's Party (WP) winning the remaining 6. The WP successfully retained their ward of Hougang SMC and captured Aljunied GRC. This marked the first time a GRC was won by an opposition party since the introduction of GRCs. As six Members of Parliament from the opposition were elected, only three Non-Constituency Member of Parliament seats were offered, one to Lina Chiam from the Singapore People's Party and the other two seats to Yee Jenn Jong and Gerald Giam from the Worker's Party. These offers were all accepted, resulting in a total of nine opposition MPs after the election.
This election marked several firsts: the total electorate exceeded 2 million, and with 94% of the seats contested, this was the "most active" election in Singapore's history between 1968 and 2011. As the presidential election occurred three months after the election, 2011 also marked its first year in Singapore since the amendment of the constitution of elected presidency in 1991 where both national elections were held in the same calendar year.
Background.
The 2011 general elections were the sixteenth general elections in Singapore and eleventh since independence. The governing People's Action Party (PAP) sought to secure their 13th consecutive term in office since 1959. This was the second election since Lee Hsien Loong became its Secretary-General.
Parliamentary reform.
On 11 March 2010 the Government tabled three bills in the parliament to amend the Constitution, the Presidential Elections Act and the Parliamentary Elections Act. These amendments reduced the number of Group representation constituencies (GRC), increased the number of Non-Constituency Members of Parliament (NCMPs) to a maximum of nine (inclusive of the number of elected opposition members of Parliament), and the number of Nominated Members of Parliament (NMPs) permanent also to nine. A one-day "cooling-off" day was implemented, during which campaigning was forbidden, with only party political broadcasts allowed. Internet campaigning was also formally legalised as a legitimate means of political campaigning. On 26 April 2010, the amendments to the Constitution were passed by a vote of 74–1 after a three-hour debate on the bill.
Political parties.
The governing People's Action Party (PAP) has been in power since Singapore's independence in 1965, and is currently led by the Prime Minister Lee Hsien Loong. Besides the ruling PAP, the other major political parties that may contest the upcoming elections are the Workers' Party of Singapore (WP) led by Low Thia Khiang, the Singapore People's Party led by Chiam See Tong which left the Singapore Democratic Alliance (SDA) in 2011, the Singapore Democratic Party (SDP) led by Chee Soon Juan, the National Solidarity Party (NSP) led by Goh Meng Seng which left the SDA in 2007, the Reform Party (Singapore) led by Kenneth Jeyaretnam, and the Singapore Democratic Alliance (SDA) led by Desmond Lim, which is composed of the Pertubuhan Kebangsaan Melayu Singapura (Singapore Malay National Organization) (PKMS) and the Singapore Justice Party (SJP). The Reform Party is the newest party and was created on 18 June 2008 and was then led by former Member of Parliament J.B. Jeyaretnam. He could have stood for election after he was discharged from bankruptcy and reinstated to the bar, however, Jeyaretnam died of heart failure on 30 September 2008 at the age of 82. His eldest son, Kenneth Jeyaretnam has since taken up leadership of the party and is now its secretary-general.
Electoral divisions.
The Electoral Boundaries Review Committee normally publishes an updated list of electoral divisions just before elections are called. Prior to the latest amendments, there were fourteen GRCs, each with five or six seats, and nine Single Member Constituencies (SMC). There were a total of 84 seats being contested in the general election of 2006.
The new electoral map for 2011 was announced on 24 February 2011.
The changes made in the electoral divisions are as follows:
Nomination.
New candidates.
A total of 78 candidates were brand-new to this election. Notable candidates out of the 24 introduced from the People's Action Party that were part of the "fourth-generation" (4G) cabinet which include the eventual fourth Prime Minister of Singapore Lawrence Wong, a future Deputy Prime Minister of Singapore Heng Swee Keat, an ex-SAF Chief and ministers Chan Chun Sing, Tan Chuan-Jin, as well as Desmond Lee and Ong Ye Kung, the sons of former MPs Lee Yock Suan and Ong Lian Ten respectively. 
There were 54 debuting candidates from six opposition party, which include Pritam Singh who made another inroad into Parliament and went on to become the Workers' Party succeeding leader in 2018, as well as Lina Loh (wife of then-Potong Pasir SMC MP Chiam See Tong), Kenneth Andrew Jeyaretnam (son of the late J. B. Jeyaretnam), Nicole Seah, Tan Jee Say, Hazel Poa (who also joined by her spouse Tony Tan Lay Thiam) and Benjamin Pwee Yek Guan.
Retiring politicians.
20 existing PAP members from the 11th Parliament will not see re-election, among which 18 announced their retirement, ten of which being office holders, and two members, Balaji Sadasivan (Ang Mo Kio GRC) and Ong Chit Chung (Jurong GRC), died during their term in office but neither by-elections were called since their wards were part of a Group Representation Constituency; the latter however would later become a Bukit Batok Single Member Constituency on the next election in 2015. Eric Low, another PAP candidate that first entered politics in the 2001 election but lost twice to WP, did not seek re-election, making him the second PAP candidate to participate but did not enter parliament (the first being Pang Kim Hin).
Staking claims.
Soon after the announcement of the new electoral boundaries, various opposition parties indicated their intent to contest, subject to negotiations between political parties to avoid three-cornered fights. The parties declaring an interest to contest each constituency and their nomination status is reflected below.
General election campaign.
Televised forum.
In the first pre-election forum of this nature in Singapore since the 1988 General Election, Channel NewsAsia invited the main parties to record an hour-long programme. The programme, in English entitled, “A political forum on Singapore's future” brought together the ruling People's Action Party (PAP) and four opposition parties to discuss long and short-term challenges for the country.
The forum included:
Social media.
The Worker's Party utilised social media to circumvent obstacles placed in front of them by Singapore's government-controlled media.
Political rallies.
The Singapore Police Force announced 41 political rally sites on 27 April which could be booked by political parties on a first-come-first-served basis. Rallies were allowed to be conducted from 28 April to 5 May, from 7am to 10pm. The 41st site is for lunch time rallies at Boat Quay near to the UOB Plaza.

Controversies.
Online video.
During the 2011 elections campaigning, Vivian Balakrishnan said the SDP was "suppressing a certain YouTube video, which raises some very awkward questions about the agenda and motivations of the SDP and its candidates". He issued the following statement:
I am not sure what [the SDP] strategy is...I can't help feeling that part of the reason for their reticence is they have elements of their agenda they are not prepared to disclose and subject to scrutiny. Eventually, they will have to come out of the closet. (The Straits Times, 20 April 2011)
Vincent Wijeysingha rejected his comments stating, "We've been a very open party and we're very clear."
This incident was cited in an article published in The Economist criticising the ruling party's election strategy The New Paper released a story next day, with the headline: Is Singapore ready for a GAY MP?" Kenneth Jeyaretnam of the Reform Party called Balakrishnan's campaign a "low attack."
Balakrishnan received widespread controversy and criticism online for his remark. On 28 April, he told the press: "there is "no need" to further discuss [the] video". He said that his question was a "legitimate".
Cooling-off day controversies.
Nicole Seah, a team member contesting Marine Parade GRC under the NSP team, filed a complaint to the Elections Department on 6 May stating PAP-team member Tin Pei Ling had violated the state-mandated cooling-off period 24 hours before polls by posting a Facebook comment "in response to a video [in the state press] that showed Seah crying after being told about a MacPherson female resident who could not get a refund of her son's $80 tuition fees".
The NSP team was advised by the Elections Department to lodge a police report before the Elections Department could investigate.
The day after the election, Seah told reporters that her party had not received any response after making the complaint, and said no decision had been taken on whether or not to pursue the issue. She added that the NSP knew "it is an uphill battle to get any results out of this. I would rather devote my time and resources to the residents".
A similar complaint was lodged against Seah alleging that material had been published on her Facebook page during Cooling-Off Day. On 10 August, the Singapore Police Force announced that it had concluded its investigations into the two incidents, and that aside from a "stern warning" to Tin's friend, neither action was taken against either Tin or Seah.
Separately, the NSP also complained that the PAP had been distributing election material to residents in Tampines GRC in violation of cooling-off regulations.
Results.
After polls closed at 8pm, vote counting began. Results were announced by Yam Ah Mee, chief executive director of the People's Association, who acted as the Returning Officer for the election. The first result was declared at 11.58pm on 7 May 2011, where PAP candidate Lim Biow Chuan won the Mountbatten SMC with a majority of 3,529.
At 1.31 am on 8 May 2011, the PAP team for Ang Mo Kio GRC was declared to have won the division, putting the PAP's seat tally at 44 seats, and thus formed the government. The final result to be declared was for the Potong Pasir SMC at 2.51am on 8 May, where the PAP won the seat from the SPP on a razor-thin margin of 114 votes.
While People's Action Party retain government control for the 13th consecutive election, PAP saw its vote majorities reduced by about 7% island-wide for a second election in a row, down to its lowest national vote share to 60.17%, surpassing 1991's share of 61.0%.
PAP won all but two constituencies with 81 out of 87 seats; the WP won the remaining six after successfully retain Hougang SMC and for the first time since GRCs were introduced in 1988, WP also won Aljunied GRC, the first instance where any opposition party won a GRC.
