Lagan Valley (UK Parliament constituency)

Boundaries

The seat was created in 1983, as part of an expansion of Northern Ireland's constituencies from 12 to 17, and was predominantly made up from parts of South Antrim and North Down in the area of the River Lagan. In their original proposals, in January 1980, the boundary commission proposed calling it "Lagan". In further revisions in 1995 it lost some areas to both Belfast West and Strangford.

Members of Parliament

MPs from Lagan Valley have included two party leaders: James Molyneaux, leader of the Ulster Unionist Party from 1979 to 1995 (having represented South Antrim from 1970 to 1979), and Jeffrey Donaldson, leader of the Democratic Unionist Party from 2021 to 2024, when he resigned as party leader and was suspended as a party member.
