# Westbury (UK Parliament constituency)

Westbury was a parliamentary constituency in Wiltshire from 1449 to 2010. It was represented in the House of Commons of England until 1707, and then in the House of Commons of Great Britain from 1707 to 1800, and finally in the House of Commons of the Parliament of the United Kingdom from 1801 until 2010.
Until 1885, it was a parliamentary borough, returning two Members of Parliament (MPs) until 1832 and only one from 1832 to 1885. The parliamentary borough was abolished in 1885, when the name was transferred to a county constituency returning one MP. Elections used the bloc vote system when two MPs were returned, and the first-past-the-post system of election when one seat was contested.
Westbury returned a Conservative Member at every election after 1924.

Originally a small pocket borough, covering only a small part of the parish of Westbury, in 1885 the parliamentary borough became a county constituency in Wiltshire. At the time of the constituency's abolition in 2010 it included the towns of Westbury, Warminster, Trowbridge, and Bradford-on-Avon, and the surrounding rural areas as far south as Mere. Until boundary changes in 1997, it also included Melksham.

### Boundary review, 2005

Following a review of parliamentary representation in Wiltshire, the Boundary Commission for England created two new constituencies in the county. Chippenham was created mostly from the adjoining North Wiltshire constituency, plus the town of Bradford-on-Avon at the northern end of the Westbury constituency, while the rest of Westbury saw minor changes to its composition and was renamed South West Wiltshire. These changes were approved in 2005, to take effect at the following general election, which ultimately took place in 2010.
