  • The table was initially based on: McGarry, J. and O'Leary, B. (eds) (1990) The Future of Northern Ireland. Oxford: Claredon Press.

  • The results of the most recent elections are based on media reports. All these figures should be treated as provisional.

  • The most meaningful comparisons are those between similar types of elections, for example when comparing Westminster elections.

  • The 1986 Westminster by-elections were held in protest against the Anglo-Irish Agreement. 15 seats were contested and one of the Unionist seats was lost to the SDLP.
