The Singapore Progressive Party (SPP) was a conservative party that was founded by a group of lawyers in 1947. Unlike the other political parties that were outrightly anti-British and pressing for Singapore’s independence, the SPP was willing to work with the British to introduce constitutional reforms and a gradual transition to self-government. However, the SPP’s pro-colonial policies did not appeal to the larger working-class electorate. It managed to secure only four seats out of the 22 it contested during the 1955 Legislative Assembly Election. In 1956, the SPP merged with the Democratic Party to form the Liberal Socialist Party (LSP). It won seven seats in the City Council Election held in 1957 and failed to win any seats in the 1959 election, thereby marking its political demise.
