The system that protected them has stopped working the way it once did
For generations, Britain's electoral architecture was engineered to concentrate power in two hands — a system that punished fragmentation and rewarded consolidation. But England's local elections of May 2026 suggest that architecture has begun to work against its original beneficiaries: Labour and the Conservatives together claimed their lowest combined vote share on record, while Reform and the Greens outpaced them in seats won. When an electorate fragments deeply enough, even a system designed to suppress challengers can become the instrument of their rise.
- Reform and the Greens together won nearly 200 more council seats than Labour and the Conservatives combined — a reversal that would have seemed impossible under the old two-party logic of first-past-the-post.
- Labour's losses were sharpest precisely where it was strongest: in defended seats, support collapsed by an average of 25 percentage points, turning former strongholds into the epicentres of defeat.
- The system's distortions have not disappeared — they have simply changed hands, handing Reform majority control of eight councils on vote shares as low as 36 percent, and delivering the Greens 56 percent of Manchester's seats on 37 percent of the vote.
- One in three of the contested councils now sits in no overall control, a dramatic surge from just six before the election, signalling that first-past-the-post can no longer reliably manufacture majorities in a five-party landscape.
- Britain may be crossing a threshold where coalition and minority governance become structural features rather than temporary anomalies, regardless of which electoral system is nominally in place.
For decades, Britain's first-past-the-post system functioned as a kind of constitutional guarantee for the Conservative and Labour parties. A candidate needed only to finish ahead of local rivals to claim a seat, and votes spread thinly across minor parties counted for nothing. The system was, in effect, a duopoly machine.
England's local elections in May 2026 suggest that machine has broken down. The BBC's national vote share analysis placed Reform first with 26 percent and the Greens second with 18 percent, while Labour and the Conservatives each managed just 17 percent — a combined 34 percent that marks a historic low. In seat terms, Reform and the Greens together won 2,063 council seats against 1,864 for Labour and the Conservatives jointly. The contrast with the 2024 general election — where those same insurgent parties won just nine seats despite over 20 percent of the national vote — illustrates how profoundly the local landscape has shifted.
The geography of collapse made things worse for the two established parties. Labour's support fell an average of 25 percentage points in wards it was defending, compared to 12 points in undefended ones. The Conservatives saw drops of 14 and 10 points respectively. Losses concentrated in their own strongholds meant the seat tallies — over 1,400 for Labour, over 500 for the Conservatives — were far steeper than a uniform national swing would have produced.
First-past-the-post still generated its characteristic distortions, but now in unfamiliar directions. Reform won majority control of eight councils on vote shares as low as 36 percent. Labour converted 29 percent of the vote into 66 percent of seats in Ealing. The Greens claimed 56 percent of Manchester's seats on 37 percent of the vote. Even the Liberal Democrats, whose support fell by four points on average, gained nearly 100 seats — simply because their opponents collapsed faster.
Yet fragmentation has exposed the system's limits. One in three of the 63 fully contested councils now sits in no overall control, up from just six before Thursday. A mechanism historically capable of manufacturing majority governments can no longer do so when votes are scattered across five or more significant parties. Britain may be entering an era in which coalition and minority governance are not exceptions to be managed, but the new political normal.
For decades, Britain's first-past-the-post electoral system worked like a machine designed to protect two parties. The Conservatives and Labour understood the rules: a candidate needed only to finish ahead of rivals in their local ward to claim the seat. Votes scattered thinly across the map meant nothing. Small parties learned early that backing them was futile. The system, in other words, was built to keep the two-party duopoly intact.
But something shifted in England's local elections on Thursday. The results suggest that first-past-the-post, that old guardian of Conservative and Labour dominance, has stopped working the way it once did. The BBC's analysis of the vote share shows Reform would have finished first nationally with 26 percent, the Greens second with 18 percent, while Labour and the Conservatives each managed just 17 percent. Their combined share—34 percent—marks a historic low. The Liberal Democrats, traditionally squeezed by the system, claimed 16 percent. This is not a minor shift. It reflects an electorate that has fundamentally fragmented.
The seat counts tell an even starker story. Reform and the Greens together won 2,063 council seats, nearly 200 more than Labour and the Conservatives managed jointly with 1,864. The Liberal Democrats added another 842. Compare this to the 2024 general election, where the same two insurgent parties won just nine seats despite capturing over 20 percent of the vote nationally. The local elections revealed what happens when first-past-the-post operates in a genuinely crowded field: the system no longer suppresses challengers. It amplifies them.
What made this worse for Labour and the Conservatives was the geography of their collapse. In wards where Labour was defending seats they already held, support dropped an average of 25 percentage points compared to four years earlier. In wards they were not defending, the drop was 12 points. For the Conservatives, the figures were 14 points in defended seats and 10 in undefended ones. This concentration of losses in their strongholds meant the seat losses—more than 1,400 for Labour, more than 500 for the Conservatives—were far steeper than they would have been if support had eroded evenly. The system, designed to cushion them, instead magnified their defeat.
Yet first-past-the-post still produced its characteristic distortions, now working in unexpected directions. Reform won majority control of eight councils despite securing less than half the vote in each. In Dudley, Plymouth, and Rochdale, the party claimed as much as 67 percent of seats on just 36 percent of the vote. Labour managed similar feats in Ealing and Merton, where 29 percent of the vote translated into 66 and 56 percent of seats respectively. The Greens won 56 percent of Manchester's seats on 37 percent of the vote. In a fragmented electorate, a relatively modest vote share can still deliver outsized power if opponents are split.
The system even rewarded parties that were losing ground. The Liberal Democrats' support fell by four percentage points on average, yet they gained nearly 100 seats because Conservative and Labour support collapsed even faster. In Westminster, the Conservatives regained control of the council despite their own vote share dropping five points—because Labour's fell by 17. When the field is crowded, winning means simply losing less than everyone else.
But fragmentation has a limit to what first-past-the-post can manage. One in three of the 63 councils where all seats were contested are now in no overall control—up from just six councils before Thursday. The system, which historically guaranteed majority governments for whoever won the electoral battle between Labour and the Conservatives, can no longer promise that outcome. Even first-past-the-post cannot manufacture a majority when votes are scattered across five or more significant parties. Britain may be entering an era where coalition and minority government become the norm, not the exception.

The Hearth Conversation Another angle on the story
Why does it matter that Reform and the Greens won more seats than Labour and the Conservatives combined?
Because for the first time in modern British politics, the electoral system stopped protecting the two major parties. First-past-the-post was designed to do exactly that—to make it pointless to vote for anyone else. Now voters have seen that their votes for smaller parties actually translate into real power at the local level.
But didn't Labour and the Conservatives still lose because people stopped voting for them?
Yes, but the system made it worse. When you're defending a seat you already hold and your support collapses, you lose it to whoever comes second. Labour lost 25 percentage points in defended wards but only 12 in undefended ones. The geography of their collapse amplified the damage.
So first-past-the-post is now broken?
Not broken exactly. It still does what it's always done—reward whoever finishes first in each ward. The problem is that when five parties are competitive instead of two, finishing first doesn't mean much. You can win a council with 36 percent of the vote. You can lose control with 29 percent. The system becomes unpredictable.
What happens next?
One in three councils are now in no overall control. That means coalitions, negotiations, minority governments. The system that was supposed to deliver strong, stable majorities can't do that anymore. Britain may have to learn how to govern differently.
Could this force a change to proportional representation?
It might. But that's a bigger question than these local elections. What's clear now is that first-past-the-post no longer works the way it did when it was designed for two-party politics.
