# 5th Parliament of Singapore

The 5th Parliament of Singapore was a meeting of the Parliament of Singapore. It commenced its first and only session on 3 February 1981 and was dissolved on 4 December 1984.
The members of the 5th Parliament were elected in the 1980 general election. Parliament was controlled by a People's Action Party majority, led by Prime Minister Lee Kuan Yew and his Cabinet. The Speaker was Dr Yeoh Ghim Seng.
Two seats were vacated during the term: on 14 October 1981, Anson's MP Devan Nair vacated his seat to assume his presidency, resulting in the first-ever presence of any opposition-elect with Workers' Party MP J. B. Jeyaretnam winning the ensuing by-election. Exactly two years later on 14 October 1983, Havelock's MP Hon Sui Sen died during the term, but a by-election was not called unlike Anson's case and thus allowing the seat to become vacant until the end of term.
