Spelthorne is a constituency in Surrey represented in the House of Commons of the UK Parliament since 2010 by Kwasi Kwarteng, a Conservative, who served as Chancellor of the Exchequer for 38 days in September and October 2022. Boundaries 1918–1945: The Urban Districts of Feltham, Hampton, Hampton Wick, Staines, Sunbury-on-Thames, and Teddington, and the Rural District of Staines. 1945–1950: The Urban Districts of Feltham, Staines, Sunbury-on-Thames, and Yiewsley and West Drayton. 1950–1955: The Urban Districts of Feltham, Staines, and Sunbury-on-Thames. 1955–1983: The Urban Districts of Staines and Sunbury-on-Thames. 1983–present: The Borough of Spelthorne (same content as above) History of boundaries Spelthorne was one of six hundreds of the historic county of Middlesex which covered its south west. It had thirteen historic parishes whereas the modern borough and seat has seven. The London Government Act 1963 placed the historic county in London except for two areas, one being the seven south-westernmost parishes of Spelthorne and Middlesex, placed since the commencement of the Act in April 1965 in Surrey. From 1885 to 1918 it was in the inceptive Uxbridge seat, before which its electorate contributed to the two-seat Middlesex constituency since the 13th century creation of the House of Commons of England. 1918-1945 The seat was created by the Representation of the People Act 1918 and amounted to the larger, slightly less built-up part of the increasingly outer metropolitan Uxbridge seat which was split, in 1918, in two. It was given county seat status for unimportant logistical purposes. It amounted to the obsolete hundred plus the small west-to-east parishes in the north of Harmondsworth, Harlington and Cranford as the seat took in seven late 19th century-formed areas of local government, including the Staines Rural District. Due to the incursion into Elthorne Hundred the seat could have more accurately been named South West Middlesex. 1945-1950 For the post-war 1945 election the seat lost an eastern section: three of the historic parishes namely Hampton, Hampton Wick and Teddington to the Twickenham seat (which shifted substantially south, shedding Labour-leaning Hounslow). The seat saw a northern exchange. It gained two small parishes (one of which, Yiewsley was of modern creation) to the NNW from its parent seat. It lost the similarly small Cranford and Harlington parishes to form, with parts of the parent seat, the new seat of Southall, which the incumbent for Spelthorne went on to represent in 1950. 1950-1955 In 1950 the seat was
