Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021.[3] Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.
The commission proposed that Wiltshire be combined with Gloucestershire as a sub-region of the South West Region, with the creation of the cross-county boundary constituency of South Cotswolds, resulting in a major reconfiguration of Chippenham. Devizes and North Wiltshire were abolished and new constituencies named East Wiltshire, and Melksham and Devizes, created.[4][5] These changes came into effect for the 2024 general election.
