It is currently the longest-running bellwether constituency in the U.K., having voted for an MP of the ‘winning’ Party (i.e. the Party that formed the government) in every General Election from 1964 onwards.

History

The seat was created under the Redistribution of Seats Act 1885. This Act added a net 18 seats, but its main purpose was to correct the over-representation of minor, if often old,boroughs and of depopulated county divisions. In their place were created new seats with a larger population. In Kent the Act finally abolished the Sandwich constituency, which sent two MPs until 1885. It also halved the representation of no fewer than four other historic towns. In contrast a seat for Dartford, the North-Western Division of Kent or North West Kent, was created.

The area of the seat, remaining a combination of urban, suburban and a small rural population, has been gradually reduced through its territory being contributed to new constituencies, their county designation later being changed in 1965 to become part of the new county of Greater London, which adjoins Dartford. These seats were Bexley, created in 1945, and Erith & Crayford, created in 1955.

Political history

In the early 20th century, the Dartford constituency was very much a bellwether. Dartford's results later shifted towards the left: in a by-election in 1938 and then in the general elections from 1951 to 1959, a Labour candidate won, going against the national result.

Since 1964, however, Dartford has alternated between Labour and the Conservatives in line with the national result, and has thus served as a bellwether again. Indeed, as of the 2024 General Election it is the longest-running bellwether constituency in the United Kingdom.^[2] 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.

Constituency profile

As its name suggests, the main settlement in the constituency is the town of Dartford, but it also includes a number of other towns and villages, including Swanscombe, Longfield and Greenhithe. These all add up to create a diverse constituency which covers urban and rural areas.

The population of the constituency currently comprises the bulk of the Borough of Dartford. It is on the border with the London Borough of Bexley, with which at one time it shared an MP.

Health and wealth of its residents is around average for the UK.^[4]
