London West (European Parliament constituency)

London West was a constituency electing one Member of the European Parliament (MEP) by the first-past-the-post system. It was created in 1979 and abolished in 1999 when it was replaced by the multi-member London Constituency, using a system of proportional representation.

European constituencies were formed by the grouping of UK Parliamentary (Westminster) constituencies.

When London West was created in 1979 it consisted of eight Westminster constituencies: Acton, Brentford and Isleworth, Ealing North, Feltham and Heston, Hayes and Harlington, Ruislip-Northwood, Southall, Uxbridge.

United Kingdom Parliamentary constituencies were redrawn in 1983 and the European constituencies were altered in 1984 to reflect this. The revised seat comprised the following Westminster constituencies: Brentford and Isleworth, Ealing Acton, Ealing North, Ealing Southall, Feltham and Heston, Hammersmith, Richmond and Barnes and Twickemham. The same boundaries were used in 1989 and 1994.

The first election in 1979 was won by Brian Hord of the Conservative Party. In 1984 Michael Elliott of the Labour Party won the seat and held it until its abolition in 1999.
