Toh Chin Chye was a Singaporean statesman and academic who served as Deputy Prime Minister of Singapore between 1959 and 1968. Toh is widely recognised as one of the founding fathers of Singapore. He was also one of the founders of the People's Action Party (PAP), which has governed the country continuously since independence.

General elections were held in Singapore on 21 September 1963, five days after Singapore became part of Malaysia. Voters elected all 51 members of the Legislative Assembly. The elections were the only ones to date with no boundary changes to any existing constituencies prior to the elections. The result was a victory for the People's Action Party (PAP), which won 37 of the 51 seats, while the majority of the remaining seats were won by Barisan Sosialis (BS).
