[n 1][n 2] The constituency was represented in Parliament by Trudy Harrison, of the Conservative Party, from a by-election in February 2017 until its abolition for the 2024 general election.

Copeland was one of five Cumbria seats won (held or gained) by a Conservative candidate in 2019 out of a total of six covering the county.

Keswick was included in the new constituency of Penrith and Solway, and Millom was transferred to Barrow and Furness.

It consistently returned Labour Party candidates until the by-election of 23 February 2017, when Trudy Harrison gained it for the Conservatives.

They included the town of Keswick, which had a larger electorate than the other three new and sparsely populated wards, despite their extensive area.
