Elections (proportional representation): Ten Minute Rule Motion

What happened: On 3 December 2024, the House of Commons passed a Ten Minute Rule motion calling for parliamentary elections to be conducted using proportional representation (PR) rather than the existing first-past-the-post (FPTP) system. The motion passed by the narrowest of margins, with 138 votes in favour and 136 against. A Ten Minute Rule motion is a procedural device allowing a backbench MP to make a brief case for a proposed bill, with one speech in favour and one in opposition, followed by a vote. It does not itself change the law but signals parliamentary interest in a topic.

Why it matters: The result is a symbolic but notable indication of sentiment within the Commons on one of the most contested questions in British constitutional politics. The current FPTP system, in which the candidate with the most votes in each constituency wins regardless of share, tends to produce majority governments from parties that win well under half the national vote. Proponents of PR argue that it would make every vote count more equally and produce legislatures that better reflect the distribution of voter opinion across the country. The motion advances no immediate policy change, but a Commons majority in favour, however slim, adds pressure on the government to consider the question seriously, particularly given that the 2024 general election produced a very large Labour majority on a relatively modest vote share.

The politics: The vote cut across party lines in complex ways. Liberal Democrats backed the motion unanimously, as did all four Plaid Cymru MPs and all four Green MPs, reflecting those parties' longstanding support for electoral reform. Conservatives voted against unanimously, as did the Democratic Unionist Party and the Ulster Unionist Party. The most revealing division was within Labour: 60 Labour and Labour and Co-operative MPs voted in favour, against 47 who opposed, while a very large number, over 290, did not vote at all. Reform UK split two each way. The motion's passage by just two votes, despite more than 300 Labour MPs being absent, illustrates both the depth of cross-party support for PR among smaller parties and the continuing ambivalence within the governing party, whose leadership has not committed to electoral reform.
