Electoral Reform Polling: 60% Now Back PR — Does It Matter?

For most of the past century, British electoral reform was a minority interest, associated principally with the Liberal Democrats and a handful of academic advocates. In May 2026, polling consistently shows 60% of British adults support replacing first-past-the-post with a proportional representation system. With Reform UK at 28%, Greens at 15%, and Liberal Democrats at 12.6%, the mathematics of the current electoral system are generating democratic legitimacy questions that cannot easily be ignored.

The 60% Polling Figure: What It Means

Multiple polls in spring 2026 have recorded majority or near-majority support for proportional representation. An Electoral Reform Society-commissioned YouGov poll from April 2026 found 61% supporting a change to a more proportional system, 22% preferring to keep first-past-the-post, and 17% unsure. A Savanta poll with a slightly different question framing found 58% supporting a “fairer system where seats match votes”, with 24% opposed. The range across all polls conducted in the first four months of 2026 is 55–64% in favour of change.

This represents a significant shift from historical norms. In 2011, when the UK held a referendum on the Alternative Vote system — not even full proportional representation but a preferential system — the AV option was defeated 68% to 32%. The same electorate that voted two-to-one against AV in 2011 is now showing 60% support for more substantial change 15 years later. The transformation reflects the dramatic fragmentation of the party system and a more widespread understanding of how votes translate into seats.

The Mathematics That Drive the Debate

The current polling situation makes the distortion produced by first-past-the-post uniquely visible. Reform UK is polling at 28% nationally but won just 5 seats on 14.3% in 2024. Under a purely proportional system, 28% of the vote would translate to roughly 182 seats in a 650-seat House of Commons. Under the current system, if Reform’s vote remains geographically dispersed, 28% nationally could still produce fewer than 100 seats.

The Greens face an even starker illustration. At 15% nationally, the party could win 97 seats under proportional representation. Under FPTP, current MRP projections suggest they might win 8–18 seats. The Liberal Democrats at 12.6% are more efficient because their vote is concentrated geographically in areas where they actually contest seats, but they too receive fewer seats than strict proportionality would deliver.

The arithmetic is stark: in the current polling environment, Reform, Greens, and Lib Dems together account for 55.6% of voting intention. Under strict proportionality, they would hold 361 seats between them — a majority. Under first-past-the-post, they are likely to hold fewer than 200 combined. Labour and the Conservatives, together accounting for 36.8% of vote share, are projected to hold more than 400 seats.

Party-by-Party Support for Electoral Reform

Support for electoral reform varies significantly by party identification, which itself reveals important information about the political incentives at play. Among Liberal Democrat voters, support for proportional representation stands at 91% — unsurprisingly, given the party’s historic position as the most disadvantaged by FPTP. Among Green voters, 87% support PR. Among Reform UK voters, a striking 74% support a change to proportional representation — reflecting the party’s calculation that its nationally dispersed vote would benefit enormously from a more proportional system.

Among Labour voters, support is more mixed: 52% back PR, 31% prefer FPTP, and 17% are unsure. The Labour split reflects the party’s internal tension between its urban progressive wing, which sees PR as a means of building a permanent progressive coalition, and its more traditional wing, which argues that FPTP has historically delivered Labour majorities that proportionality might prevent. Among Conservative voters, 44% back PR — notably higher than one might expect from a party that benefited most from FPTP in recent history, and reflecting current Tory voters’ disillusionment with a system that has just delivered their worst-ever electoral result.

The Labour Government Position

Despite 60% public support for PR, the Labour government has been explicit that it does not intend to introduce electoral reform. Keir Starmer’s position is that Labour was elected on a programme that did not include changing the voting system, and that introducing such a change without a specific manifesto commitment or a referendum would be constitutionally inappropriate. He has also argued privately, according to briefings from Westminster sources, that a majority Labour government has no incentive to change a system that gave it 63% of seats on 33.7% of votes in 2024.

This position is politically rational but carries long-term risk. If the 2029 election produces a hung parliament — which current polling makes the likely scenario — smaller parties are virtually certain to demand electoral reform as a condition of any confidence and supply arrangement. In that scenario, the question is not whether reform happens but which system is chosen and how quickly.

What System Do People Actually Want?

When pollsters ask about specific alternative systems rather than proportional representation in the abstract, the picture becomes more complex. Among the 60% who support PR in principle, the most popular specific system is the Additional Member System, used for Scottish Parliament and Welsh Senedd elections, which combines local constituency MPs with regional list members to produce a broadly proportional result. Around 38% of PR supporters cite this as their preferred model.

Single Transferable Vote, the system used in Northern Ireland and the Republic of Ireland, is preferred by approximately 28% of PR supporters. Pure party list systems, more common in continental Europe, are less popular at 34%, with many voters preferring systems that retain some form of local representation. The Alternative Vote system — defeated in the 2011 referendum — has revived slightly in popularity, with 18% of PR supporters seeing it as an acceptable compromise, though it is not actually proportional.

Does the 60% Figure Actually Matter?

The critical question for electoral reform advocates is whether 60% public support translates into political pressure sufficient to change the system. Historical precedent from other countries suggests that electoral reform typically requires not just public opinion but a specific political moment: usually a hung parliament or coalition negotiation where smaller parties have leverage. The 1996 New Zealand reform, 2011 Scottish independence referendum, and various European changes all came from political crisis rather than simple polling majorities.

In the UK, the most likely pathway to electoral reform is a 2029 hung parliament. In that scenario, if Reform UK, the Liberal Democrats, and the Greens are all at the negotiating table, their collective demand for PR would be backed by their combined vote share — potentially over 55% of the national vote — and would be very difficult for a minority Labour or Conservative government to resist. The 60% polling figure matters primarily because it gives political cover for any party that agrees to such demands during coalition negotiations.

The answer to “does it matter?” is therefore: not yet, but potentially enormously. If the 2029 election produces the hung parliament that current polling suggests is likely, the 60% support for PR will become one of the defining policy arguments of the post-election negotiation. Whether that produces a referendum, a direct change, or another delay depends on the specific arithmetic of a Parliament not yet elected. What is certain is that the democratic legitimacy of first-past-the-post has never been more publicly questioned.
