Although the People's Action Party had won 43 seats in the 1959 elections, they lost four seats in 1961. A further 13 legislators were expelled from PAP for voting against the government in a no-confidence motion on 20 July 1961; the dissidents subsequently formed a new party, the Barisan Sosialis, alleging PAP as a communist front. The combination of by-election defeats, defections and expulsions reduced the PAP by 17 seats down to 26, leaving PAP with a one-seat majority. On 3 July 1962, while the integration referendum debate was in procession, PAP lost its majority following the resignation of legislator Ho Puay Choo. Five days later, UPP legislator S. V. Lingam returned to PAP fold, giving it back its one-seat majority, but five days later, PAP lost its majority again after health minister Ahmad Ibrahim died from liver cancer. BS initially planned to field its iconic leader, Lim Chin Siong, in the vacated seat, but the Prime Minister Lee Kuan Yew opted against a by-election, and instead called a fresh election. On 31 August 1963, Singapore was declared independent with PAP declared as trustees until the merger with Malaysia could be complete. On 3 September, Lee dissolved the Legislative Assembly in accordance with procedure, and called for elections to be held on 21 September.
Timeline
Campaign
The elections, held in the midst of Singapore's merger with Malaysia, are remembered as the PAP's most hard-fought election, as the party fielded a full slate and faced intensive challenges from three components that did nearly the same. BS collated with Parti Rakyat, and fielded candidates in all but two seats, while UPP had an unusual large number of candidates. The PAP government launched Operation Coldstore on 2 February 1963 and detained several BS leaders, including Lim. On the final night of campaigning, PAP officials warned that should BS win the election and defeat PAP, the Malaysia Federal government could send troops into Singapore to invoke emergency powers in place of the incoming government led by the new pro-communist party, leaving no opportunity for BS to respond. This was said to have accounted for the eventual victory of the PAP the following day. The sole Workers' Party legislator David Marshall resigned from the party he founded and became the only independent. Another participant was Singapore Alliance, an extension of the ruling federal Alliance Party in Malaysia, which was a coalition consisting of the Singapore People's Alliance along with the local branches of UMNO, the Malayan Chinese Association and Malayan Indian Congress. However, former Chief Minister and leader Lim Yew Hock opted not to run in the elections, citing a defamation campaign by the PAP.
Results
The PAP won a landslide victory, securing a two-thirds majority, an outcome that had been in doubt or unexpected in the lead-up to the vote. However, the party's vote share was its lowest-ever at just under 47%. Despite the BS and UPP winning a combined 14 seats, both parties failed to win most of the seats they contested, due to the split of the anti-PAP vote. A total of 92 candidates lost their deposits. The Singapore Alliance lost all seven seats it had held before dissolution, losing even in core support areas such as Malay constituencies Kampong Kembangan, Geylang Serai and Southern Islands. Nine incumbent members lost their re-election on the election, among which the defeats of Kenneth Michael Byrne and Tan Kia Gan marked the first time a higher-ranked PAP cabinet minister had been defeated in their constituencies. This would not happen again until the 2011 elections, 48 years and 11 elections later, where cabinet ministers Lim Hwee Hua and George Yeo were defeated in his constituency of Aljunied.

Aftermath
Many cited factors that led to the PAP victory include:
The PAP's eleventh hour warning to voters that Malaysia would send troops into Singapore and invoke emergency powers in place of the incoming the Barisan government;
A strong support among voters for Singapore's merger with Malaya, which was perceived to be jeopardised should Barisan win the election due to its opposition to merger;
English-educated middle classes fearful of communism tactically voting for PAP following the split of the leftists away from the party.
Barisan's support for Indonesia and the Communist Party of Indonesia's oppositions to the formation of Malaysia, especially when Indonesia had declared Konfrontasi and begun provocative military manoeuvres in Borneo in the lead up to the election;
To discourage future defections, the PAP government passed a constitutional amendment stipulating that legislators who resign or are expelled from the parties they were elected under would lose their seats. As a result, by-elections were subsequently held in Hong Lim in 1965, seven constituencies in 1966 and five constituencies in 1967. Those victories resulted PAP in achieving a parliament monopoly that would last for the next 15 years until the first elected opposition MP in 1981. The distribution of 15 Singapore seats in Malaysia's lower house of Parliament was based on the outcome of the election. PAP was allocated 12, which were given to Prime Minister Lee, Deputy Prime MinisterToh Chin Chye, ministers Goh Keng Swee, Ong Pang Boon, S. Rajaratnam, Yong Nyuk Lin, Jek Yeun Thong, Lim Kim San, Othman Wok and assembly members Abdul Rahim Ishak, Wee Toon Boon and Ho See Beng. BS was allocated 3: Chia Thye Poh, Lim Huan Boon and Kow Kee Seng.
