Sedgefield (UK Parliament constituency)

Sedgefield was first created under the Representation of the People Act 1918 for the 1918 general election, comprising primarily southern parts of the abolished South Eastern Division of Durham, including the communities of Segefield and Billingham. It also included parts of the former Mid Durham seat (Ferryhill) and a small area transferred from Bishop Auckland (Chilton).

It was abolished for the February 1974 general election, when its contents were distributed to the neighbouring seats of Bishop Auckland (Darlington RD), Durham (Sedgefield RD), Easington (Stockton RD) and Teesside, Stockton (Billingham UD).

The constituency was recreated at the next redistribution, which came into effect at the 1983 general election, with similar boundaries, but excluding Billingham and Newton Aycliffe and including Spennymoor.

Minor changes – the Rural District of Stockton had been altered, absorbing the Rural District of Hartlepool, but losing Billingham to a new urban district.

From 1955, the boundaries of the Rural Districts of Darlington, Sedgefield and Stockton were altered in line with changes to local authority boundaries.{{UK SI|year=1970|number=1674|section=|url=http://www.legislation.gov.uk/uksi/1970/1674/pdfs/uksi_19701674_en.pdf|title=The Parliamentary Constituencies (England) Order 1970|isbn=|made=11 November 1970|laid=11 November 1970|force=25 November 1970}} pp 10-11

Spennymoor and Tudhoe transferred from North West Durham; remainder of District of Sedgefield wards from Durham; District of Easington wards from Easington; and Borough of Darlington wards from Bishop Auckland.

Minor changes only to reflect redrawing of local authority ward boundaries.

In the 2009 structural changes to local government in England, the local authority districts in Durham were abolished and replaced with a single unitary authority; however, this did affected the boundaries of the constituency.

The 2023 review of Westminster constituencies recommended that all wards in the Borough of Darlington should be removed from the seat, with Shildon moving in from Bishop Auckland and Coxhoe from City of Durham. The reconfigured seat would be renamed "Newton Aycliffe and Sedgefield".

From its recreation in 1983 until 27 June 2007, the Member of Parliament was Tony Blair, who led a successful campaign for his party to win the 1997 general election in a landslide and thereafter served for ten years as prime minister, leading the campaigns at two subsequent general elections. Blair was the first Prime Minister to lead the Labour Party to three consecutive victories. He resigned as the Member of Parliament for Sedgefield on the same day as he resigned as prime minister, which triggered a by-election.[http://news.bbc.co.uk/1/hi/uk_politics/6243558.stm Blair resigns as prime minister], BBC News, 27 June 2007

At the by-election on 19 July 2007, the official Labour Party candidate Phil Wilson was elected on a reduced majority which in national terms is safe instead of marginal. While Wilson had never came close to the enormous majorities held by Blair during his tenure as MP and only secured an absolute majority of the vote for the first time at the 2017 general election, he consistently had majorities of over 6,000 votes in every election at which he had stood.

At the 2019 election, the Conservatives' candidate Paul Howell defeated Wilson with a majority of 4,513 and a swing of 12.8%. Sedgefield was one of the net gain of 48 seats in England by the Conservatives, as well as being considered part of the so-called "Red Wall".

Sedgefield has a long mining history (extracting coal, fluorspar and iron ore) and once had a very strong affiliation to the Labour Party, with nearly monolithic support in parts of the constituency.{{Citation needed|date=August 2020}} The area contains a mixture of former coal country in the area around Trimdon and more industrial areas around the new town of Newton Aycliffe. The construction of a new Hitachi factory created 730 jobs in the town.{{cite web |title=Hitachi's £82m train factory opens |url=https://www.bbc.com/news/uk-england-tees-34130229 |publisher=BBC News |date=September 3, 2015}} There are also more prosperous parts of the constituency that form the bulk of the Conservative vote – for example, the ancient market town of Sedgefield itself, with a charter dating back to 1312. The outer suburbs of Darlington are also relatively wealthy, as well as Hurworth-on-Tees, where unemployment stands at just 1.0%.{{cite web |title=Tees Valley Ward Statistics |url=https://teesvalley-ca.gov.uk/InstantAtlas/WARDS/report_Ward_I299_2017.html}}

;In statistics

The constituency consists of Census Output Areas of two local government districts with similar characteristics: a working population whose average income is lower than the national average and close-to-average reliance upon social housing.{{cite web|url=https://www.ons.gov.uk/help/localstatistics|title=Local statistics – Office for National Statistics|website=www.ons.gov.uk}} At the end of 2012 the unemployment rate in the constituency stood as 5.0% of the population claiming Jobseekers' Allowance, compared to the regional average of 5.5%.[https://www.theguardian.com/news/datablog/2010/nov/17/unemployment-and-employment-statistics-economics Unemployment claimants by constituency] The Guardian

The local authority contributing to the bulk of the seat has a middling 27.2% of its population without a car, a high 27.5% of the population without qualifications and a medium 21.5% with level 4 qualifications or above. Darlington has 28% of its population without a car, 24.8% of the population without qualifications and a medium 23.7% with level 4 qualifications or above.

In terms of tenure 65.8% of County Durham homes and 64.9% of Darlington homes are owned outright or on a mortgage as at the 2011 census.{{cite web|url=http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-interactive-content/index.html|archive-url=https://web.archive.org/web/20160129132219/http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-interactive-content/index.html|url-status=dead|title=2011 census interactive maps|archive-date=29 January 2016}}
