At the 2024 general election Labour won 411 seats on 34.6% of the vote in Great Britain, giving it a large Commons majority. Reform UK won 14.7% of the vote but only 5 seats, while the Liberal Democrats won 72 seats on 12.6%.
The result is one of the clearest recent illustrations of how first-past-the-post turns votes into seats, rewarding parties whose support is concentrated or efficiently spread across constituencies.

The contrast between Reform UK and the Liberal Democrats is particularly useful. Reform UK won more votes but far fewer seats, because Liberal Democrat support was concentrated in winnable constituencies.
The result revived debate about electoral reform and about whether the UK is now multi-party in votes but still two-party in seats.
Defenders argue that a clear majority lets a government carry out its manifesto and be judged on it at the next election, which proportional systems may not provide.
The Liberal Democrats’ seat total reflects targeted campaigning. FPTP rewards geographical concentration, which some see as representing local communities rather than as a flaw.
Labour and the Conservatives still won 532 of 650 seats, so in Parliament the UK remains largely two-party.
The facts and their significance still stand.
The clearest recent votes-to-seats evidence for any FPTP or party system question.
