Crawley is a constituency[n 1] in West Sussex represented in the House of Commons of the UK Parliament since 2024 by Peter Lamb of the Labour Party.

The Boundary Commission analysed population increase and recommended that changes to the constituency be made for the 2010 general election so the seat is now coterminous with the borough.

Psephologists and editors have long identified[citation needed] the marginality of most of the largest new towns and outer satellite cities in Southern England as to those seats with a workforce across diverse sectors (e.g. Bristol, Exeter, Gloucester, Milton Keynes, Hemel Hempstead, Reading, Southampton, Portsmouth, Dover).

Few communities in these seats are rooted in Victorian villa toryism nor in Labour's heartlands that for decades depended on heavy industry (the main coalfields, the Lancashire Mill Towns, the Potteries/Black Country, steelworking, dockworking and shipbuilding areas).

[5] Smith's later majorities have been 6,526 in 2015; and 2,459 in 2017, elections where the Liberal Democrats, Scepanovic, along with the 2017 candidate for East Worthing and Shoreham in West Sussex lost their deposits by failing to attract 5% of the vote.
