North Cornwall (UK Parliament constituency)

North Cornwall is a constituency represented in the House of Commons of the UK Parliament by Ben Maguire, a Liberal Democrat since the 2024 general election. Like all British constituencies, the seat elects one Member of Parliament (MP) by the first past the post system of election at least every five years. The seat was created in 1918. Since 1950, the constituency has been held by MPs from either the Conservative Party or the Liberal Democrats (including the party's predecessor, the Liberal Party).

History
This constituency was created under the Representation of the People Act 1918.

With exceptions in 1997, 2001 and 2019, the seat's margin of victory has been less than 20% of the vote. It has been consistently fought over between and won by the Conservative Party and the Liberal Democrats' candidate (or predecessor party in the latter case), and can be considered a marginal seat. In 1997 and 2001 the seat turned out strongly overall for the latter party. However, in the 2019 general election, the Conservatives won a large majority of 28.6% over the Liberal Democrat candidate.

A third-placed (other party) candidate has not polled more in North Cornwall than 16.38%, which took place in 1951. The seat saw three years of defection of its Liberal MP to join the post-World War II Attlee Ministry however in 2015 saw the lowest share of the Labour Party's vote nationally – reinforcing a consistent result by a great majority supporting left-wing politics to vote for a Liberal and later Liberal Democrat at general elections since the seat's inception.
