Prior to the 1997 general election, various organisations carried out opinion polling to gauge voting intentions.
Results of such polls are displayed in this list.
Most opinion polls do not cover Northern Ireland, since its 18 seats were not contested by the political parties standing for election in the rest of the United Kingdom.
By the end of 1992 Labour had established a lead over the Conservatives which lasted until the 1997 election.
