1987 United Kingdom general election in Scotland
A general election was held in the United Kingdom on Thursday, 11 June 1987 and all 72 seats in Scotland were contested. While the Conservatives under Margaret Thatcher comfortably won a majority across the United Kingdom, the result saw the Conservatives suffer significant losses in Scotland as their vote share declined significantly in what The Glasgow Herald called "the humiliation of the Tories north of the border." Labour, who as well as gaining seats from the Conservatives also took two from the SNP and one from the SDP, now had more MPs from Scotland than at any other point in the party's history, including holding every seat in Glasgow, while the Conservatives were reduced to their lowest number since the Second World War.
