If you voted in 2024, your ballot likely elected no one. In 85% of British constituencies, more people voted against the winning candidate than for them. One voter in three cast a tactical ballot, meaning they chose someone other than their actual preference because their preferred candidate had no chance of winning where they live.

Zoom out, and the pattern gets sharper. Labour took 411 seats, 63% of the Commons, on 33.7% of the vote. Reform UK won half a million more votes than the Liberal Democrats and ended up with 67 fewer seats. The Greens took close to two million votes and four seats. By any standard, this was the most disproportionate election in British history.

None of this is a glitch. It is the system working exactly as it has always worked. Unless something changes, it will keep working this way, with results that may look very different by 2029.

This piece argues three things. The case for changing the voting system does not depend on which party you support; it depends only on whether you think your vote should count. The moment to actually change it is narrower than most people realise, because every party that has ever supported electoral reform has dropped it at the moment of victory under the current system. And the way to fix it does not require importing a system from somewhere else. It requires designing one that fits Britain.

How a third of the vote becomes two-thirds of the seats

The mechanism is simple enough that it sounds reasonable until you look at what it does. In each of 650 constituencies, whoever gets the most votes wins the seat. There is no second round, no ranking, and no requirement to pass 50%. If five candidates split the vote and one of them gets 28% while the other four get 18% each, the 28% candidate wins. The 72% who voted for someone else get nothing.

Multiply that across 650 seats, and you get the Commons we currently have. A government with two-thirds of the seats on a third of the votes. A party, Reform, that came third in the popular vote and won five seats. A party, the Liberal Democrats, that came fourth in votes and third in seats, because its support is concentrated rather than spread. The system does not weigh votes by intensity or by reasoning. It weighs them by geography. A Liberal Democrat vote in a Conservative–Liberal Democrat marginal is worth, in seats, perhaps a hundred times a Liberal Democrat vote in central Liverpool. The two voters cast identical ballots. The system treats them as fundamentally different.

This is why the cross-party point matters. The Reform voter in a Labour-safe seat is in exactly the position the Green voter is in a Conservative-safe seat: voting, and seeing nothing happen as a result. So is the Tory in Bristol and the Labour voter in Surrey. The question of whether votes should count cannot honestly depend on whose vote it is. A principle of “everyone’s vote counts equally” that only applies when your side benefits is no principle at all.

The objection is that FPTP delivers stability: strong single-party governments, clear mandates, decisive change. The technical claim that FPTP produces single-party majorities is true. The implied claim that this delivers stability does not survive the decade we just lived through. Britain had five Prime Ministers between 2016 and 2024. Four of them took office without an election. One lasted 45 days. The Conservatives lost half their vote share and 244 seats between 2019 and 2024. A system that turns small movements in opinion into political earthquakes is not stable. The numbers add up; it is the word “stability” being asked to carry more weight than it can.

Why every push for reform has failed, and why this one might not

The piece could stop there. The case against FPTP is settled enough that you could read most of it on a campaign leaflet. The harder question is why, given that the system is so visibly broken, Britain has not changed it.

The answer is structural. Every party that has supported electoral reform has dropped it the moment it stood to win under the system it wanted to change.

Labour is the clearest case. The 1997 Labour manifesto committed to a referendum on the voting system. Tony Blair set up the Jenkins Commission, which reported the following year and recommended a system called AV+. The referendum was never held. Labour won three elections under FPTP, and the question quietly disappeared from the agenda. In September 2022, with the party in opposition and facing another likely defeat, the Labour conference voted overwhelmingly to commit the next Labour government to introducing proportional representation in its first term. In late 2023, the party’s National Executive Committee changed the rules so members would influence policy primarily through the National Policy Forum rather than through conference motions. The 2024 manifesto contained no commitment to electoral reform. For thirty years, Labour has supported PR when it was losing and forgotten it when it was winning. This is not about any individual leader being dishonest. It is about an incentive that operates on whoever holds the leadership.

The live version is happening now. Two years ago, Nigel Farage was calling FPTP “outdated” and “not fit for purpose.” His then-leader, Richard Tice, said in 2024 that Reform’s aim was to win enough votes to pressure a new Labour government into reforming the system. Since polls began showing Reform could win under FPTP, support among Reform voters for keeping the system has risen from 17% to 31% in a single year. The party that was loudest in demanding reform is rediscovering, in real time, the convenience of the status quo.

Two parties have held the line: the Liberal Democrats and the Greens. The Liberal Democrats have benefited from FPTP in pockets, with their 72 seats in 2024 roughly matching their vote share, and have remained pro-reform anyway, which is to their credit, though perhaps that would be different if they had a realistic chance of forming long-term governments under FPTP. The Greens have a member-controlled policy structure that makes it harder for a future leadership to abandon the position than it would be for a more leadership-driven party. But the structural lesson holds. PR is supported, in any given parliament, by the parties that do not yet think they will benefit from FPTP. That is precisely why change has to come from voters, not parties. No party in power has an interest in delivering it.

The window in which no single party is confident of winning under FPTP is historically brief. The current moment is unusually open. The Senedd just held its 2026 election under full proportional representation. The Lords lost its hereditary peers at the end of April 2026, leaving the chamber smaller and more in flux than at any point since 1999. Public support for PR sits at 45–49%, against 24–26% for FPTP, with majorities of Labour, Liberal Democrat, Green and Reform voters supporting change. Only Conservatives are split. This is the most reform-friendly political moment in a generation.

It is also, almost certainly, going to close. The moment Reform’s leadership concludes that the current system will deliver them power, and they are visibly approaching that conclusion, the party drops PR. If Labour’s leadership concludes that a second landslide is more attractive than a fairer system, it does the same. Britain has been here before. The reform window of 1997–2001 closed because Labour won and no longer needed it. The window of 2010–2015 closed because the Conservatives won outright in the election that followed. The window opens when the parties capable of closing it are uncertain. It is open now.

The objection to all of this is the obvious one. If no party in power has an interest in delivering reform, what makes any of them deliver it? The answer is that none of them does, until the cost of refusing gets higher than the cost of delivering. Parties respond to incentives, not principles. The Brexit referendum happened because UKIP took enough Conservative vote share to make refusing one more expensive than offering one, not because David Cameron changed his mind on Europe. The Liberal Democrats lost 49 of their 57 seats in 2015 because voters who felt betrayed on tuition fees made abandoning a flagship pledge ruinously expensive, not because the party rediscovered its principles in time. New Zealand changed its voting system in 1993 because a non-binding referendum the year before returned an 85% mandate for change that no government could survive ignoring. None of these required politicians to act on conscience. They required voters to make the alternative unaffordable. That is the mechanism, and it is the only one that has ever worked. Reform-supporting voters do not need to persuade Labour or Reform that PR is right. They need to demonstrate, in how they vote and how they stop voting, that abandoning it now costs more than delivering it. The parties are reading the room correctly when they keep FPTP. They will read the room correctly when they don’t.

Designing a British answer

Three off-the-shelf proportional systems are on offer. Each gets something right and gives up something Britain has historically valued.

The Single Transferable Vote, used in Ireland, is properly proportional and maintains a local link, but does so by creating large multi-member constituencies in which voters rank candidates rather than choosing one. The ballot is more demanding, and the single-named MP for a small area disappears. The Additional Member System, used in Germany, Scotland and Wales, combines constituency MPs and list MPs in a single chamber. It is proportional, but it creates two tiers of MPs sitting alongside each other: those with a constituency and those without, and the list MPs tend to be treated by voters and by the other MPs as second-class. List PR, used in much of continental Europe, is the cleanest version of proportionality but severs the local link entirely. You vote for a party and get whoever the party puts at the top of its list.

Britain doesn’t have to pick any of them. It can build the one that fits modern Britain by weaving in what has traditionally worked for us.

Here is what that could look like. One ballot, two votes. You vote for the person you want to represent your area, and you vote for the party you want to form the government. The two votes elect two chambers on the same day, in the same election. You could vote for a representative from the same party that you voted for, but you also might decide that there’s a party you would prefer to vote for, and a representative from a different party, or from no party at all, who is the best placed to stand up for the interests of your constituency.

The party vote elects a chamber that is fully proportional, using D’Hondt, a formula used across most of Europe, that allocates seats to match vote share as closely as possible. This chamber is the government-forming one. The Prime Minister and the Cabinet come from it. The party or coalition that commands a majority governs the country. Because seats match votes, the government in this chamber actually reflects how Britain voted. That is, if 20% vote for a party, 20% of this chamber comes from that party, and that party gets 20% of the say in any votes.

The local vote elects a separate chamber that replaces the House of Lords. It has one member per constituency, chosen in the same way MPs are now. It keeps the scrutinising and delaying powers the Lords currently has, the ability to revise legislation, send it back, slow it down, but stops short of a permanent veto on what the government was elected to deliver.

The relationship between the two chambers is the relationship Britain already has, applied to the chambers that now deserve those roles. The Commons currently overrides the Lords because the Commons is elected and the Lords is not. Under this system, both chambers are elected, but the proportional chamber is the one that reflects how the country actually voted, while the constituency chamber reflects how it voted geographically. The proportional chamber inherits the supremacy the current Commons holds, for the same reason the current Commons holds it: it has the stronger democratic claim. The constituency chamber inherits the revising role, for the same reason the current Lords holds it: it brings a different lens to legislation, slows down bad law, and forces second thoughts. The Parliament Acts already exist for the moment the two disagree. They keep working. Nothing about this requires inventing a new constitutional doctrine; it requires applying the existing one to the chamber that now has the better claim to it.

This is also the chamber that, finally, makes the second chamber of Parliament something other than an inheritance from a thousand years of accommodations. Even after the hereditary peers were removed in April 2026, the Lords still has around 730 unelected legislators, including bishops, and remains the second-largest legislative chamber in the world, exceeded only by China’s National People’s Congress. Replacing it with an elected chamber accountable to the people it serves is overdue, regardless of what happens to the Commons.

Parties standing for the proportional chamber publish, before the election, three things: the person they would make Prime Minister, the people from whom they would draw their Cabinet, and the full slate of candidates who might sit as their MPs. They govern from those lists. A party serious about contesting government publishes a pool large enough to absorb five years of normal politics: a full slate of constituency candidates and several dozen potential ministers. In a single-party government it will appoint a fraction of that pool. In a coalition where it holds three ministries it will appoint fewer still. The electorate’s interest is not in seeing exactly who serves; it is in having seen, before voting, the people who could. A reshuffle within the pool is routine politics. A reshuffle that reaches outside it, a friend of the Prime Minister, a donor, a newly minted peer, is the move the election trigger exists to prevent. What’s blocked is the bait-and-switch, not the reshuffle.

The published-list mechanism is what makes the system honest. It is the constitutional discipline that closes the gap between what voters are told before an election and what they get after it. Consider the actual reality of Britain since 2016. Theresa May replaced David Cameron, Boris Johnson replaced May, Liz Truss replaced Johnson, and Rishi Sunak replaced Truss, with no public vote at any stage. The published-list system makes that impossible. Coalitions assemble their Cabinet from the published lists of the parties involved, so every minister in every conceivable government has already been put before the electorate.

Three objections need answering.

The first is the standard complaint that proportional systems produce coalitions, which means backroom deals and broken promises. Coalitions in this system are more transparent than single-party governments under FPTP, not less. Every Cabinet is built from publicly named candidates that the country has already seen. The bait-and-switch, a party campaigning on one leadership team and governing with another, is impossible by design. The coalition system being criticised is, in practice, more democratic than the single-party system being defended.

The second is that the change is too complex, that voters lost the 2011 AV referendum because the proposal asked them to learn a new system, and a more elaborate package would lose by more. The premise mistakes complexity for the voter with complexity for the designer. From the voter’s side, the change is small. There is one ballot, with one new box on it: tick the party you want to govern. The election happens on the same day it always has. Both chambers are filled in one go, so there is no extra trip to the polling station and no separate Lords election to track. A voter who wants to vote the same party twice can do so without thinking about it. A voter who wants to split their ticket, a Labour government with a Lib Dem local representative, a Green government with an independent voice for their town, can do that too. The arithmetic that turns those votes into seats is more elaborate than counting crosses in a column, but D’Hondt is the same arithmetic used in nearly every European democracy, and the Scottish Parliament, the Senedd and the London Assembly already use related methods. None of these has produced a confused electorate. The complexity is in the parliamentary plumbing, which the voter never has to see.

The third is the practical worry that published lists will run out: over five years of deaths, retirements, scandals, and defections, a party might exhaust the list it published. Parties publish lists long enough to last; a party that somehow exhausts its list sees its bloc in Parliament shrink until the next election. For the rare case of a genuine national emergency requiring a temporary government, the system provides for it. None of these edge cases is harder to handle than the edge cases the current system handles routinely.

First-past-the-post was not designed. It accreted over centuries from medieval county and borough representation. The House of Lords was not designed either. It is the residue of a thousand years of ad hoc accommodations between kings, churches and aristocracies. The British constitution is the only major democratic constitution in the world that nobody ever sat down to write. That has produced flexibility. It has also produced a chamber of around 730 unelected legislators, a Commons that turns a third of the vote into two-thirds of the seats, and an electorate where a third of voters cast a ballot for someone they did not actually want.

A British proportional representation isn’t a foreign import. It is the chance to choose what Britain currently inherits: to keep what works about the Westminster tradition, replace what does not, and build a second chamber that is finally accountable to the public. The argument for doing it now isn’t that the moment is ideal, but that the moment exists at all. And it won’t for long.
