Colchester is a constituency in Essex represented in the House of Commons of the UK Parliament since 2024 by Pam Cox, of the Labour party. The seat was previously held by Conservative MP Will Quince who announced in June 2023 that he would not be standing for re-election.

Constituency profile

Once the basis for one or two semi-rural seats, the modern-day Colchester constituency is a compact, urban core, containing the town centre and surrounding neighbourhoods. The present Colchester constituency most closely resembles the old seat of Colchester North, which was held by the Conservative Bernard Jenkin from 1992 to 1997. The seat has one of Britain's largest residential military populations.

History

The Parliamentary Borough of Colchester had sent two members to the Parliament of England since the Model Parliament of 1295 until 1707, then to the Parliament of Great Britain from 1707 to 1800 and to the Parliament of the United Kingdom from 1801. In 1885, it was one of 36 English boroughs and three Irish boroughs to have its representation reduced to one under the Redistribution of Seats Act 1885. Under the Representation of the People Act 1918, the Parliamentary Borough was abolished and replaced with a Division of the County of Essex (later a County Constituency). The revised constituency remained virtually unchanged until it was briefly abolished for the 1983 general election following the Third Periodic Review of Westminster Constituencies, but re-established for the 1997 general election as a Borough Constituency by the Fourth Review. In 1997, the vote was split three ways with the Liberal Democrat candidate Bob Russell winning with a small majority. Russell increased his votes and percentage share in next three elections. In the 2010 election this was the only non-Conservative seat in Essex. Russell was defeated in the 2015 general election by Conservative Will Quince, by an 11.5% majority. In the 2017 election Quince was re-elected by a slightly decreased margin by percentage (10.6%), with Labour moving into 2nd place after a substantial increase in their vote. In the 2019 election, Quince increased his majority to 9,423 or 17.6% in percentage terms. The seat lost the ward of Old Heath and The Hythe in the 2023 Boundary Commission review but despite this, Colchester was won by Labour for the first time since 1945 in the 2024 United Kingdom general election with Pam Cox as the new MP. The Liberal Democrats came fourth, narrowly behind Reform UK.

Boundaries and boundary changes

1918–1950

The area comprising the Rural District of Lexden and Winstree had largely been part of the Harwich Division.

1950–1983

No changes (the Urban District of West Mersea had been formed as a separate local authority in 1926). For the 1983 general election, the constituency was abolished, with the northern parts (comprising the majority) forming the bulk of the new constituency of North Colchester. Southern areas were included in the new constituency of South Colchester and Maldon.

1997–2010

Re-established as a Borough Constituency from parts of the abolished constituencies of South Colchester and Maldon (Berechurch, Harbour, New Town, Prettygate and Shrub End wards) and North Colchester (remaining wards).

2010–2024

''Local authority wards redistributed. Minor reduction in electorate, with Stanway ward being included in the new constituency of Witham.''

Current

Further to the 2023 Periodic Review of Westminster constituencies, which came into effect for the 2024 general election, the composition of the constituency is as follows (as they existed on 1 December 2020): The revised contents closely correspond to the previous boundaries, with the exception of the Old Heath and The Hythe areas to the south east of the city centre, which are now included in Harwich and North Essex.
