The Local Government Act 1972 moved the District of Mid Sussex into West Sussex from East Sussex. This change was put into effect in the Parliamentary constituency boundaries for the 1983 boundary changes.
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain the existing 8 constituencies in West Sussex, with minor changes to realign constituency boundaries with those of current local government wards, and to reduce the electoral disparity between constituencies.
See 2023 Periodic Review of Westminster constituencies for further details.
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 West Sussex with East 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.[4] [5]The following constituencies were proposed:
Containing electoral wards from Adur
Containing electoral wards from Arun
Containing electoral wards from Chichester
Containing electoral wards from Crawley
Containing electoral wards from Horsham
Containing electoral wards from Mid Sussex
Containing electoral wards from Worthing
