North Cornwall is a constituency[n 1] represented in the House of Commons of the UK Parliament by Ben Maguire, a Liberal Democrat since the 2024 general election.

However, in the 2019 general election, the Conservatives won a large majority of 28.6% over the Liberal Democrat candidate.

This was overturned in the 2024 general election when the Liberal Democrats recaptured the seat with a majority of 19.4%.

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.

1918–1950: The Borough of Launceston, the urban districts of Newquay, Padstow, Stratton and Bude, and Wadebridge, the rural districts of Calstock, Camelford, Launceston, St Columb Major, and Stratton, and parts of the rural districts of Bodmin and Holsworthy (these areas such as Whitstone and Week St Mary were on the Cornish side of the border).
