New Conservative associations come into force to align with the Parliamentary constituencies as a result of the 2023 Boundary Commission Review.
As such. Wealden will cease to exist -- parts to the west (Uckfield, Buxted, Forest Row, Danehill and Maresfield) being transferred to the new constituency of East Grinstead and Uckfield. Arlington ward will move wholly into Lewes constituency. The remainder of the present Wealden will join with Heathfield and other areas to the east (including Five Ashes, Cowbeech, Cross-in-Hand and Punnetts Town) to create the new Sussex Weald.
Until the next General Election, which will be contested on the new boundaries, MPs continue to represent constituents as present - that is on the 2019 boundaries they were elected on.
