Hove and Portslade is a borough constituency in East Sussex represented in the House of Commons of the UK Parliament since 2015 by Peter Kyle of the Labour Party, who currently serves as Secretary of State for Science, Innovation and Technology in the government of Keir Starmer.

The settlement of Hove is an economically active seaside resort which is both a commuter town and centred in an area of high local employment, stretching from Portsmouth to London Gatwick Airport.

Hove was a Conservative stronghold until the 1997 general election, when the Labour Party saw a landslide parliamentary victory and with it, as in Greater London, wide success on the developed East Sussex coast.

Weatherley stood down after one term, and the 2015 election saw Peter Kyle regain the seat for Labour on a 3.1% swing.

Brighton and Lewes prior to 1950 Peter Kyle's 21.8% vote share increase was the 5th largest for any Labour Party candidate at the 2017 election.
