The 1987 United Kingdom general election was held on Thursday 11 June 1987, to elect 650 members to the House of Commons. The election was the third consecutive general election victory for the Conservative Party, who won a majority of 102 seats and second landslide under the leadership of Margaret Thatcher, who became the first Prime Minister since the Earl of Liverpool in 1820 to lead a party into three successive electoral victories.

The Ulster Unionist Party (UUP) is a unionist political party in Northern Ireland. The party was founded as the Ulster Unionist Council in 1905, emerging from the Irish Unionist Alliance in Ulster. Under Edward Carson, it led unionist opposition to the Irish Home Rule movement. Following the partition of Ireland, it was the governing party of Northern Ireland between 1921 and 1972. It was supported by most unionist voters throughout the conflict known as the Troubles, during which time it was often referred to as the Official Unionist Party (OUP).
