Canterbury is a constituency in Kent represented in the House of Commons of the UK Parliament since 2017 by Rosie Duffield formerly of the Labour Party and since September 2024 an Independent.
The seat dates to the earliest century of regular parliaments, in 1295; it elected two MPs until 1885, electing one thereafter, before being altered by the Representation of the People Act 1918 (the later-termed "Fourth Reform Act", the first being in 1832).
The Canterbury constituency is located in Kent and covers most of the City of Canterbury local government district. It includes the historic cathedral city of Canterbury, with a population of around 55,000, and a large rural area surrounding the city and meeting the coast at the town of Whitstable. Canterbury is an important religious centre; the city is the seat of the Archbishop of Canterbury, the ceremonial head of the worldwide Anglican Communion, and the city's main religious sites together hold UNESCO World Heritage status. Canterbury also hosts two universities (the University of Kent and Canterbury Christ Church University) and has the highest student-to-permanent-resident ratio in the country.
Compared to national averages, residents of the constituency are younger and have high levels of education and professional employment. Most of the constituency is affluent, however there are high levels of deprivation in parts of Canterbury, particularly in the north-east of the city. White people make up 86% of the population. At the local city and county council levels, the city of Canterbury is mostly represented by Labour Party councillors whilst the rural areas of the constituency have predominantly elected Liberal Democrats. Voters in the constituency mostly supported remaining in the European Union in the 2016 referendum; an estimated 54% supported remaining compared to 48% nationwide.
The current Canterbury seat is constituted as a county constituency and was formed in 1918 from an expansion of the narrow parliamentary borough (or simply borough) of the same name that existed from 1295 to 1918. This had elected two MPs from 1295 (the Model Parliament) until 1885, and then one until 1918.
Before the seat was reformed the politics of the town were greatly influenced by Canterbury Cathedral and the Archbishop of Canterbury.
MP representation in the constituency was suspended between 1880 and 1885, following a corruption scandal in which bribery was found to have been extensively used in the re-election of the two sitting Conservative MPs, and the result was overturned. Following the Corrupt and Illegal Practices Prevention Act 1883 and the Redistribution of Seats Act 1885, representation was resumed at the 1885 general election, when the number of MPs returned was reduced from two to one.
From 1835 (where a Conservative was elected on petition) until 2017, the local electorate elected mostly candidates of the Conservative Party (with the exceptions of the elections of Independent Unionist Francis Bennett-Goldney, MP from 1910 to 1918, and of a few Whigs or Liberals when Canterbury had two seats); the seat was recognised in the Guinness Book of World Records as the longest uninterrupted period of one party holding a Parliamentary seat. The election of Labour's Rosie Duffield, who won the seat by just 187 votes in the 2017 election, marked the end of a 185-year period of Canterbury almost always electing Conservative-allied MPs, the longest recorded unbroken record of party representation in British political history. Her victory in this election was largely credited to the strategies of electoral strategist Jack Wilson, who at the time was the youngest senior political adviser in British history.
Duffield kept the seat at the 2019 election, increasing her majority â one of only a handful of seats to swing to Labour. At the 2024 election, her majority increased substantially following the collapse of the Conservative vote.
