Keir Starmer’s Nightmare – a look ahead to the May 7 elections

The UK is facing unprecedented electoral times. For the first time in British history, a party other than Labour or the Conservative Party has led in the polls for over 12 months. A governing party has never fallen in the opinion polls as fast or as heavily as the current Labour government. Fewer than two in five people say they would vote for Labour or the Conservatives, which has never happened before. To help us make sense of these seismic changes, esteemed political scientist and elections expert Sir John Curtice joined GK Strategy and our guests to explain the fundamental shifts that have taken place in electoral behaviour in the UK, and to unpack what this means for the upcoming elections on May 7.

On May 7, millions of people across the United Kingdom will go to the polls to vote in this important set of elections. Around 5000 seats across 136 local councils in England, which includes all the London borough councils, are up for grabs. Outside of England, Scotland and Wales will have parliamentary elections which will determine what party will run the devolved governments in Edinburgh and Cardiff. These elections are the biggest set of elections between now and the next general election, and the results will inevitably have a significant impact on politics and the standings of the current party leaders.

Curtice explained that British electoral attitudes have become highly fragmented, with the underlying shift being visible in the breakdown of traditional voting predictors. Historically, working-class and younger voters tended to support Labour, while middle- and upper-class and older voters leaned Conservative. However, his analysis of the 2024 general election showed that these relationships have largely collapsed. In their place, voting behaviour is increasingly structured around social values: whether individuals are socially liberal, and view diversity as something to be promoted, or socially conservative, and favouring greater cultural homogeneity.

This shift first became apparent during the Brexit referendum. While there was a relatively even split between economically left- and right-wing voters on whether to remain in or leave the EU, social attitudes were far more polarised: social liberals overwhelmingly supported Remain, while social conservatives backed Leave. Curtice argued that Brexit crystallised this realignment in British politics, with social values now serving as the strongest predictor of voting behaviour.

Looking to the elections on May 7 and the fate of the two main parties, Curtice laid out a grim picture for them both. He warned that the pro-Brexit coalition which delivered Boris Johnson’s victory in 2019 has now fractured, leaving the Conservative vote split almost evenly between Leave and Remain supporters. For Labour, the picture that Curtice painted is arguably worse, with its 2024 coalition fragmenting across the Green Party, Reform UK, and the Liberal Democrats. Curtice argued that the driving factor behind this is that both the Green party and Reform UK have firmly chosen a side on the socially liberal–socially conservative divide, allowing them to reap the electoral rewards of modern Britain’s voting behaviour.

May 7 looks to be a dark night for Labour and the Conservative Party, with Curtice stating the night will either be “bad, very bad, or existential” for them both. Polling day could result in what Curtice described as “Keir Starmer’s Nightmare”: Labour coming third in Wales and Scotland, losing to Reform UK in working class councils, and the Green Party beating them in London. While he acknowledged the considerable uncertainty around the elections and their outcomes, Curtice argued that the two-party system is effectively dead. In its place, the first-past-the-post system that once enabled the Conservatives and Labour to dominate is now contributing to their decline. Sir John aptly captured it: “those who live by the sword can die by the sword.”
