Dartford (UK Parliament constituency)

Dartford is a constituency in Kent represented in the House of Commons of the UK Parliament by Jim Dickson of the Labour Party since 2024.

It is currently the longest-running bellwether constituency in the UK, having voted for an MP of the party which formed the government in every General Election since 1964.

Constituency profile

The Dartford constituency is located in Kent and lies just outside the boundaries of Greater London. It is roughly coterminous with the local government district of the same name. The constituency covers the large town of Dartford and its surrounding settlements, including the small town of Swanscombe and the villages of Greenhithe, Longfield and Maypole. Dartford has an industrial heritage and was a centre for cement, flour and paper manufacturing until the decline of industry in the 20th century. Today Dartford serves as a commuter town and is connected to central London by the Southeastern and Thameslink rail services.

Compared to the rest of the country, residents of the constituency have average levels of education and professional employment and above-average household income. At the 2021 census, White people made up 73% of the population, Black people were 11% and Asians were 10%. At the local borough council, most of the constituency is represented by Conservatives with some Labour councillors in Swanscombe and parts of Dartford. At the county council, all wards in the constituency elected Reform UK councillors. Voters in the constituency strongly supported leaving the European Union in the 2016 referendum, with an estimated 64% in favour of Brexit. Candidates for the largest two parties nationally have also polled first and second since 1923 in Dartford.

This was the first constituency contested by future Prime Minister Margaret Thatcher (then Margaret Roberts). She was the Conservative candidate at the 1950 and 1951 general elections, unsuccessful on both occasions.
