Barisan Sosialis
Singapore became an independent country in 1965, and at the first post-independence general election in 1968, the People's Action Party (PAP) won all 51 of the seats in Parliament after the main opposition party at the time, the Barisan Sosialis, boycotted the elections. The PAP maintained this 100% electoral record at the 1972, 1976 and 1980 general elections and all intervening by-elections up to 1981.
