While much of Europe embraces hard-right parties, the UK has swung wildly to the left. Here’s why

LONDON — A somewhat strange and ironic political shift has gripped Europe over the last few years.

In the formerly Brexiting, euroskeptic U.K., the pendulum has just swung back to the center-left Labour Party, which comes to power after a mammoth election win, ending 14 years of Conservative Party rule.

A different picture is playing out in much of western Europe — and in countries that disdained Brexit and the U.K.’s populist trend in recent years over the last decade or so. These states are now seeing their own electorates shift to the right, with nationalist, populist and euroskeptic parties riding high in voter polls and entering the corridors of power.

While the U.K. and mainland Europe are heading in different directions politically, analysts say that the driving force behind changing patterns at the polls is fundamentally the same: voters are desperate for change.

“There’s an anti-incumbency mood again in Europe,” Dan Stevens, professor of politics at Exeter University, told CNBC. No matter who the incumbent is, Stevens said, “there’s just a general dissatisfaction and want for change.”

Tapping into the zeitgeist among British voters, the U.K.’s Labour Party used “change” as its rallying cry for voters ahead of Thursday’s general election, which it won with a landslide.

The shift to the left comes after a tumultuous period in British politics during the last series of Conservative governments, with immigration concerns and euroskepticism culminating in the 2016 referendum to leave the EU. More challenges followed throughout the Covid-19 pandemic, war in Ukraine and a cost-of-living crisis. By the time the British election was called, Brits were just fed up, analysts said.

The U.K. is not alone in looking for a political change of scenery. A similar shift has been observed in much of western and eastern Europe in recent years, with hard-right populist and nationalist parties upsetting and unseating the old political establishment.

Italy, the Netherlands, Germany and France have all seen far-right parties — such as Fratelli d’Italia, the Party for Freedom, Alternative for Germany or National Rally — rise up in opinion polls or win elections.

Such parties often emerged as protest factions, standing on an anti-immigration or euroskeptic platform, but they’ve since taken a more mainstream approach to attract a wider section of the electorate, who are concerned over broader universal issues such as jobs, education, healthcare, national identity and the economy.

The latter issue is a particular driver of voting change, with rising food and energy costs and declining disposable household incomes having the most direct and decisive impact on voters.

“If you have very poor economic performance, then you would expect the political pendulum to swing, and when it swings it, it goes to the other side from where it is at present … It is swinging because people are hard up and aggravated. It’s as simple as that,” Christopher Granville, managing director of EMEA and global politics at TS Lombard, told CNBC, signaling that the turn of tide has not favored incumbent leaderships.

“Of course, there’s a huge debate about the extent to which the respective governments are responsible for this poor economic performance … You can argue that they’ve been disastrously incompetent or you can argue that they’ve been innocent victims of external shocks, such as the energy crisis provoked by the war in Ukraine, the cost of living crisis etc,” Granville added.

“Wherever you stand on that debate, the reality is the same, that the voters wants to swing the pendulum.”

Furthermore, the center-right European People’s Party — made up of Christian democratic, conservative parties across the EU — still retained its dominance in the parliamentary chamber, winning 188 seats.
