Northavon (constituency)

The constituency was established in 1983. Held initially by the Conservative Party, it was gained narrowly by the Liberal Democrats in 1997. The Almanac of British Politics described it as "one of the most unexpected Liberal Democrat gains" of the 1997 election and speculated that a significant amount of tactical voting had benefitted the party in this seat.^[2] The seat then swung heavily in the Liberal Democrats favour in 2001 and was held again by the party in 2005.

Northavon covered the same area as the former Northavon district (the more rural part of the current South Gloucestershire district) at its creation, but some of the constituency moved to Bristol North West with the boundary review implemented in 1997. The constituency included suburban and industrial areas on the outskirts of Bristol and several dormitory towns and small villages.

Following the review by the Boundary Commission for England of parliamentary representation in the former Avon county, taking effect at the 2010 general election, the Northavon seat has been abolished. It has been largely replaced by the Thornbury and Yate seat, but also by Filton and Bradley Stoke.^[3]
