Acton in Middlesex, 1918–45Acton in Middlesex, 1945–50Map that gives each named seat and any constant electoral success for national (Westminster) elections for Middlesex, 1955 to 1974.
Third (final) version of the seat (at centre). Result in Oct. 1974.
A redistribution of Parliamentary seats, which took effect at the 1950 United Kingdom general election made no change to the boundaries; its legislation, affecting election expenses and returning officer re-classified, the seat as a borough constituency.
In the redistribution which took effect at the February 1974 general election, the seat to the west, Ealing South, was abolished and this seat absorbed most of its area to reach the electoral quota, it having been heavily underweight in electorate. The seat in statute and statutory instrument became variously Ealing: Acton and/or simply Acton where under a heading of London Borough of Ealing. From the review effective from the election of 1983 it became Ealing Acton.
