Scottish Conservative Party
In Scotland, the Conservatives used to be known as the Unionist Party and were Scotland's largest party during the 1950s. However in 1965, the Scottish Unionist Party merged with the Conservative Party which triggered a decline in Conservative support across Scotland. At the 1987 General Election, the Conservatives were reduced from 21 to 10 Scottish seats, and the party lost all of its Scottish seats in 1997.
