The constituency covers most of the northern third of
Wiltshire. However it excludes the eastern town of
Swindon which is represented as
North Swindon and
South Swindon.
North Wiltshire constituency was formed by a renaming for the
1983 general election, with boundaries identical to the former Chippenham constituency (1885–1983).[4] The constituency sits between the
Cotswolds and
Swindon. Its main towns are
Calne,
Royal Wootton Bassett (a town which was a
borough constituency until abolished as a
'rotten borough' in 1832),
Cricklade and
Malmesbury, and it also contains a number of villages, both small and large, spread over a large area of farming countryside, including the well-known (often-painted and photographed) village of
Castle Combe.
For the
2010 general election the North Wiltshire
constituency changed radically as a result of boundary change recommendations. The constituency now covers a northern swathe of the previous version retaining the towns of Malmesbury, Cricklade, Royal Wootton Bassett and Calne[n 3] while the largest southern town of
Chippenham was given its own seat (which was previously abolished in 1983) that brought in the nearby market towns of
Bradford on Avon and
Melksham including parts of other seats.[5]
While North Wiltshire has a long history of returning Conservative candidates, its district council (created in 1973 and abolished in 2009) was closely contested between the Conservatives and the Liberal Democrats with many electoral wards being
marginal.
