of Surrey's seats — it contains about 20% of the county's commercial/industrial property, including large plants or wholesale units of Complete Cover Group, Kingston Technology, Edmundson Electrical, Esso Petroleum, Johnson & Johnson Vision Products, Thames Water, Shepperton Film Studios, wholesalers and storage companies. Major offices/creative facilities of BP (its global HQ), Del Monte, NatWest, Samsung, Richmond Film Services and film/television ancillary businesses are in the constituency. During the 2016 referendum on the UK's EU membership, the majority of voters in the area voted in favour of exiting the European Union. This was the preferred outcome of Spelthorne MP Kwasi Kwarteng. History of results The 1918 to 1945 broadest, initial version of the parliamentary division saw no marginal majorities and can be squarely analysed as a Conservative safe seat based on length of party tenure and size of majorities. In the 1945 general election George Pargiter (Lab) was elected in the Attlee Ministry landslide while the boundaries of the seat saw a favourable form to the party during expansion of London when the area extended to areas to the north, including Feltham and Bedfont (removed in 1955 — see Feltham and Heston) and had cast off Hampton, Hampton Wick and Teddington, before 1945 part of the seat. Since the 1955 boundary reduction and a local emphasis or demand upon private housing relative to social housing, the reduced area has eight Conservative candidate majorities of greater than 11% and three lower majorities: 1966, 1997 and 2001. The earliest of these produced the narrowest margin of victory, 5% of the vote. Based on length of party tenure and majorities the seat would be considered safe by most UK electoral analysts including of academic standing. Members of Parliament The constituency's first MP was Philip Pilditch, an architect who piloted the Ancient Monuments Act 1931 through Parliament: see Scheduled Monument. The MP for Spelthorne since 2010 is the former Chancellor Kwasi Kwarteng.
