Ealing North (UK Parliament constituency)

Ealing North is a constituency, created in 1950. Since the 2019 general election, it has been represented in the House of Commons of the UK Parliament by James Murray of the Labour Co-operative party. 
History.
Straddling the Western Avenue and directly south of Harrow, Ealing North occupies the north-western part of the London Borough of Ealing, and from the February 1974 to 2005 general elections inclusive, it was a Labour-Conservative marginal, being won by the party forming the government, and thus a bellwether. Since 1997, it has become an increasingly safe Labour seat, with the party now holding a majority of nearly 20,000 as of 2017.

Boundary review.
Following its review of parliamentary representation in North London, the Boundary Commission for England made some minor changes to Ealing North. Part of Greenford Broadway ward, along with tiny parts of Hobbayne ward and Dormers Wells ward were transferred from Ealing North to the constituency of Ealing Southall. Tiny parts of Hobbayne ward and Dormers Wells ward were exchanged in return. Parts of Ealing Broadway ward and Hanger Hill ward were removed to the new Ealing Central and Acton constituency which now avoids containing part of the London Borough of Hammersmith and Fulham.
