The 1983 United Kingdom general election in Northern Ireland was held on 9 June with 17 MPs elected in single-seat constituencies using first-past-the-post as part of the wider general election in the United Kingdom. This was an increase of five seats, after the House of Commons (Redistribution of Seats) Act 1979 had come into effect to account for the reduced representation after direct rule had been imposed since 1972. New constituencies were drawn up in 1982.[1]
In December 1985, all Unionist MPs resigned their seats in opposition to the Anglo-Irish Agreement and sought re-election in by-elections. These resulted in a loss of one seat to the SDLP
