Voices: Poll of the day: As voters turn away from Labour and the Tories, is Britain’s two-party system crumbling?

The overnight results from Thursday’s elections have sent shockwaves through Britain’s political landscape, raising serious questions about the future of the country’s traditional two-party dominance.

Reform UK, long seen as a fringe challenger, won the Runcorn and Helsby by-election by just six votes, overturning a massive 35-point Labour majority. Nigel Farage’s party also claimed its first mayoralty in Greater Lincolnshire.

Early local election results suggest Reform is on track for significant gains, particularly in areas that voted heavily for Brexit.

Both Conservatives and Labour are feeling the strain. The Tories have suffered heavy losses, while Labour’s wins have come on sharply reduced vote shares.

Meanwhile, smaller parties like the Greens and Liberal Democrats have made modest progress, though they still face challenges breaking through at scale.

Polling expert Sir John Curtice says the results underline a long-term shift in voter loyalties, as frustration with both main parties fuels growing support for alternatives like Reform and others.

For the first time in decades, he argues, no single party – or even pair of parties – appears to dominate the political scene.

As one Independent reader observed: “This election is a double-edged sword. People are turning back to the same promise-makers who failed them – yet it might finally break our two-party system.”

So we’re asking: is the era of two-party dominance over?
