Over 100 MPs sign amendment calling for electoral reform

The government is coming under increasing pressure as MPs from across Parliament call for a review of Westminster’s First Past the Post voting system.

Over 100 MPs have now signed an amendment to the Representation of the People Bill calling for a National Commission on Electoral Reform.

Tabled by Chair of the APPG for Fair Elections Alex Sobel MP, the amendment now has more signatories than any amendment of its kind to a bill this parliament.

Speaking on PoliticsHome’s The Rundown podcast, Sobel said “We've got two-thirds of seats, the Labour Party, on a third of the vote... if you look at recent council elections, Reform won two-thirds of the seats on a third of the vote in more than one local authority. So the system is shattered. It's a 19th century voting system in a 21st century political reality, and the two things need to come to a head.”

This amendment follows a set of elections widely hailed by experts as representing the end of Britain’s traditional two-party system.

Reacting to May’s election results Luke Tryl, More In Common, said “Our politics has become way more fragmented… I can pronounce death for the two-party system”. This follows a February letter, signed by 50 leading academics, warning the Government that in a multi-party age First Past the Post is “creating new risks for Britain”.

In his post-elections analysis, Sir John Curtice said the results “raise questions about whether first-past-the-post will continue to benefit the Conservatives and Labour in future. Rather, they have shown that the system is colour blind in how it operates”.

Hannah White, Director of the Institute for Government, said “These elections have provided further evidence that the fracturing of British politics is not a temporary aberration – as the Conservative and Labour parties appear to have been hoping – but a phenomenon which is here to stay… This could raise the public salience of long-standing calls for electoral reform in a way not previously seen in the UK.”

Three key factors have shifted the debate on electoral reform in recent years:

  • Public support: 53% of the public now support Proportional Representation, up from 27% in 2011. This includes a plurality of voters for all major parties, including Reform UK and the Conservatives. BSA 2026.

  • Political support: A voted in favour of PR passed in Parliament for the first time ever in December 2024. Hansard

  • Electoral fragmentation: Following May’s elections, Sir John Curtice projects five parties to win over 15% of the vote nationally, creating the prospect of seats and future general elections being won on 30% of the popular vote or less. BBC May 2026
