Boundary changes

2010 Under the fifth periodic review of Westminster constituencies, the Boundary Commission for England decided to retain the existing 8 constituencies in East Sussex, with minor changes to realign constituency boundaries with those of current local government wards, and to reduce the electoral disparity between constituencies.

For the 2023 periodic review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine East Sussex with West Sussex as a sub-region of the South East Region, resulting in the creation of a new cross-county boundary constituency named East Grinstead and Uckfield. The resultant changes to existing constituencies entailed the abolition of Wealden and the creation of the new constituency of Sussex Weald. Brighton Kemptown was renamed Brighton Kemptown and Peacehaven, and, although its boundaries were unchanged, it was proposed that Hove be renamed Hove and Portslade.

The following constituencies were proposed:

Containing electoral wards from Brighton and Hove

Brighton Kemptown (part) Brighton Pavilion Hove and Portslade

Containing electoral wards from Eastbourne

Eastbourne

Containing electoral wards from Hastings

Hastings and Rye (part)

Containing electoral wards from Lewes
