Close

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 seat takes in the cathedral and university city of Canterbury, rural villages to the south, and the seaside resort of Whitstable to the north. Full time students make up around a quarter of the electorate.^[3]

Constitutional status of seat

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.

Political history

Before the seat was reformed the politics of the town were greatly influenced by Canterbury Cathedral and the Archbishop of Canterbury.^[4]

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. ^[5]

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 – 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.
