The previous Westbury constituency was abolished: the northern part (including the town of Bradford-on-Avon) was transferred to the reinstated Chippenham seat, and the southern part (including the towns of Trowbridge, Warminster, and Westbury) formed the bulk of this constituency, which to complete it, received a minority of wards from the Salisbury seat.
Boundaries
Map of current boundaries
2010–2024: The former District of West Wiltshire wards of Dilton Marsh, Ethandune, Mid Wylye Valley, Shearwater, Southwick and Wingfield, Summerham, Trowbridge Adcroft, Trowbridge College, Trowbridge Drynham, Trowbridge John of Gaunt, Trowbridge Park, Warminster East, Warminster West, Westbury Ham, and Westbury Laverton, and the former District of Salisbury wards of Donhead, Fonthill and Nadder, Knoyle, Tisbury and Fovant, and Western and Mere.
In order to bring the electorate within the permitted range, Tisbury and the Nadder Valley were transferred to Salisbury. The village of Hilperton was added from Chippenham, while several rural parishes east of Trowbridge were transferred to Melksham and Devizes.
Constituency profile
As well as the county town of Trowbridge and the former market towns of Westbury and Warminster (the latter with a considerable Army presence), the seat covers a large rural area with smaller settlements. Residents' health and wealth are around the UK average.[4]
^As with all constituencies, South West Wiltshire elects one Member of Parliament (MP) by the first past the post system of election at least every five years.
