The Death of Britain's Two-Party System – A Century in the Making

What this episode covers

In this episode of the Explaining History Podcast, I examine the slow-motion collapse of the political order that has defined British politics for a century – and what is likely to replace it.The term "political earthquake" gets overused. What is happening in Great Britain is more like a once‑in‑a‑century end of a political order. It began in 2024 with the death of the Conservative Party – a party that is unlikely to restore itself. And it will continue over the next few years with the death of the Labour Party.The May local elections, just a week away, will mark a major step. Labour is almost certain to lose two of the places it has dominated for generations: Wales (for a century) and London (for half a century). But this isn't just about one bad election night. It is the culmination of decades of neoliberal economics, deindustrialisation, austerity, and the systematic destruction of any alternative vision within the mainstream parties.I draw a historical parallel with the last time Britain's party system realigned: the years after the First World War, when the Liberal Party – the party of 19th‑century capital, free trade, and limited government – collapsed, replaced by a two‑party system of Labour and Conservatives. That system, cemented in 1945, survived for nearly eighty years. Now it is dying.The culprits are not just individual leaders. Thatcherism broke union power, atomised communities, and left Britain poorer and more unequal. The 2008 financial crisis blew up the economic assumptions of that model. Brexit smashed Britain's role as a transatlantic bridge between Washington and Brussels. Austerity killed hundreds of thousands, collapsed public services, and turned the country into a nation in de‑development. The Labour right's merciless destruction of the Corbyn movement left the party in the hands of a centrist technocrat, Keir Starmer – a man who, despite his blandness, has gleefully embraced racist rhetoric on immigration, supported Israel's genocide in Gaza, and handed state functions over to private equity vultures.Starmer's Labour has tried to tack to the right, hoping that voters will hold their noses and vote for "not far‑right". But that strategy is failing. In recent by‑elections, voters ignored Labour's warnings and voted Green or Plaid Cymru – proving that the old "vote for us or you'll get the fascists" threat no longer works.So what comes next? The beneficiaries are two very different parties. Reform UK – funded by a reclusive Bitcoin billionaire, backed by the propaganda channel GB News – offers a populist, proto‑fascist nationalism. The Green Party – untainted by private donations, hostile to the tabloid press, and offering a genuine left‑wing economic alternative – has already won a stunning by‑election on an anti‑racist, cost‑of‑living platform.The next decade could see Britain's political landscape transformed. A two‑party system of Reform and Greens is possible – though each would feel like an enemy occupation to the other side's voters. What is certain is that the old order is being taken out to a field and put out of its misery. And what caused it? Five decades of neoliberalism – an economic project that both main parties embraced, whose contradictions they are now incapable of addressing.Explaining History helps you understand the 20th Century through critical conversations and expert interviews.
