South West Norfolk is a constituency represented in the House of Commons of the UK Parliament since 2010 by Liz Truss of the Conservative Party, who briefly served as Prime Minister of the United Kingdom from September to October 2022.

Constituency profile 
This is a rural constituency which retains a significant agricultural and food-production sector. The population is largely White and predominantly homeowners, with incomes and house prices slightly below the UK average. Electoral Calculus describes this as a "Strong Right" seat characterised by socially conservative values and strong support for Brexit.

History 
Under the Redistribution of Seats Act 1885, the three two-member county divisions of Norfolk were replaced with six single-member divisions, including the newly created South-Western Division of Norfolk, largely formed from southern parts of the abolished Western Division, including Thetford. From the 1950 general election onwards, it has been formally known as the county constituency of South West Norfolk.

South West Norfolk has been held solidly by Conservatives since 1964, but for twenty years prior; it had been ultra-marginal. Labour first held it briefly from 1929 to 1931, and Sidney Dye of the Labour Party gained it in 1945 with a narrow majority of 53 votes. Dye subsequently retained the seat at the 1950 general election with an increased, but nevertheless, small majority of 260 votes. He lost it to Denys Bullard of the Conservatives in 1951 by 442 votes and regained the seat from Bullard in 1955 with a small majority of 193 votes. Dye died at the end of 1958, and at the by-election, the Labour Party candidate Albert Hilton retained the seat with an increased majority of 1,354 votes. At the 1959 general election that soon followed, Hilton's safe majority was drastically reduced to a thin margin of 78 votes.

Although Labour had held the seat at two general elections, despite two consecutive overall Conservative victories; the Conservatives won the seat at the 1964 general election, which was a Labour victory nationwide, and the party returned to government after 13 years in opposition. Paul Hawkins, then Gillian Shephard held the seat. Shephard's majority was slashed at the 1997 general election, in what would be the worst defeat nationwide for the Conservative Party in 91 years, before recovering at the 2001 general election. Both occasions resulted in an overall Labour victory.

Shephard decided not to run again in 2005 and was elevated to a peerage. The Conservative Party selected Christopher Fraser, former MP for Mid Dorset and Poole North and he was elected with a comfortable majority of over 10,000 votes.

On 28 May 2009, Fraser announced that he would be standing down at the 2010 general election citing family reasons. This was after his expenses claims were highlighted in The Daily Telegraph; according to the newspaper, Fraser claimed £1,800 in public money for buying 215 trees and marking out the boundary of his second home in the constituency.

Liz Truss was elected to succeed Fraser at the 2010 general election, which saw the Conservatives return to government after 13 years in opposition; however, the party went into a coalition with the Liberal Democrats. Truss served as a Cabinet minister under various Conservative prime ministers since 2014, serving as Environment Secretary between 2014 and 2016 under the leadership of David Cameron, Secretary of State for Justice and Lord Chancellor between 2016 and 2017 under the leadership of Theresa May, and Secretary of State for International Trade and President of the Board of Trade between 2019 and 2021 under the leadership of Boris Johnson; before she was promoted to serve as Foreign Secretary in 2021. In 2022, Truss won the 2022 Conservative leadership election that followed Boris Johnson's decision to stand down as UK Prime Minister and Leader of the Conservative Party, and was subsequently appointed Prime Minister by Queen Elizabeth II on 6 September. Truss resigned as Prime Minister of the United Kingdom on 25 October 2022.
