1950–1955: The Urban Districts of Bredbury and Romiley, Cheadle and Gatley, Hazel Grove and Bramhall, and Marple. 1955–1974: The Urban Districts of Cheadle and Gatley, Hazel Grove and Bramhall, and Marple, and the Urban District of Bredbury and Romiley except the part of Bredbury ward added to the County Borough of Stockport by the Stockport Order 1952. 1974–1983: The Urban Districts of Cheadle and Gatley, and Wilmslow. 1983–2010: The Borough of Stockport wards of Cheadle, Cheadle Hulme North, Cheadle Hulme South, East Bramhall, Heald Green, and West Bramhall. 2010–present: The Borough of Stockport wards of Bramhall North, Bramhall South, Cheadle and Gatley, Cheadle Hulme North, Cheadle Hulme South, Heald Green, and Stepping Hill. When originally created in 1950, Cheadle was a county constituency and its area was predominantly urban in the south-eastern suburbs of the Manchester conurbation, and relatively affluent. The growth of suburbs of Manchester led to a rapidly rising electorate from the late 1950s and by the 1970 election there were 107,225 electors and some reduction was inevitable. At the February 1974 general election the seat was re-classified as a borough constituency and split in two, with the eastern parts forming the new Hazel Grove constituency. As a result of changes to the county boundaries, the constituency crossed between Greater Manchester and Cheshire. Realigning with the county boundaries in 1983, the constituency was redrawn, losing Wilmslow to Tatton and smaller parts to Macclesfield and Stockport.
Members of Parliament
The current MP is the Conservative Mary Robinson, who defeated Mark Hunter in the 2015 general election. From 1974,, Cheadle had safe Conservative majorities until the 1997 election, when the Liberal Democrats reduced the margin to around 3,000 votes. Patsy Calton scraped home in 2001 by a majority of 33 votes, the narrowest in the House of Commons, but returned with a much safer 4,000 votes in 2005. She died on 29 May 2005, triggering a by-election in July 2005, where Mark Hunter was elected with a majority of 3,657. Although held by Hunter in 2010, the Conservatives regained the seat in 2015 and held it in 2017 and 2019, albeit with reduced majorities on each occasion.
The Cheadle constituency underwent minor boundary changes after the 1992 general election and as such the change in share of vote is based on a notional calculation.
Elections in the 1980s
The boundaries of the constituency changed in 1983. Changes in the vote are based on the estimated results for 1979 had the 1983 boundaries been in operation then.
Elections in the 1970s
After the 1970 general election, boundary changes created the Hazel Grove constituency which reduced the size of the Cheadle one. The previous Member of Parliament for Cheadle, Dr Michael Winstanley became the first member returned by Hazel Grove.
