1990 Upper Bann by-election

The 1990 by-election in Upper Bann was caused by the death of the sitting Ulster Unionist Party Member of Parliament Harold McCusker on February 2 1990.

The by-election was especially notable for three reasons. Firstly, eleven candidates stood in the by-election, which to date is the record for a parliamentary election in Northern Ireland. Secondly, amongst the eleven were candidates for the Conservative Party and the Social Democratic Party, both contesting parliamentary elections in Northern Ireland for the first time since the "Equal Citizenship" campaign had sought to get the major UK parties to organise in the province. Finally the successful Ulster Unionist candidate was David Trimble, who five years later would become the leader of the party.
