On 9 August 1965, Singapore was declared as an independent sovereign state, and the Legislative was reformed as Parliament of Singapore. 1968 was the first post-independence election, which saw PAP winning every one of 58 contested seats (51 by a walkover, and the other seven on polling day), due to the election boycotting of the main opposition party at the time, the Barisan Sosialis, leading to the mass arrests of most of its leadership since 1963.
