List of parliamentary constituencies in Wiltshire



The ceremonial county of Wiltshire, England, which includes the Borough of Swindon, is divided into eight Parliamentary constituencies. They are all county constituencies.

2024
See 2023 Periodic Review of Westminster constituencies for further details.

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. 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. These changes came into effect for the 2024 general election.

The following seats were proposed:

Containing electoral wards in Swindon


 * East Wiltshire (part)
 * Swindon North
 * Swindon South

Containing electoral wards in Wiltshire (unitary authority)


 * Chippenham
 * East Wiltshire (part)
 * Melksham and Devizes
 * Salisbury
 * South Cotswolds (parts also in the Districts of Cotswold and Stroud in Gloucestershire)
 * South West Wiltshire

2010
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase the number of seats in Wiltshire from 6 to 7, with the re-establishment of Chippenham, which impacted on neighbouring constituencies. An adjusted Westbury constituency was renamed South West Wiltshire.
