Across Western Europe, the left has regained the initiative after years in which the populist right seemed to own the momentum; yet from London to Paris and Madrid, the same paradox is emerging. The bolder the advance, the greater the risk of frightening the moderate voters without whom no progressive government can win — or survive.
United Kingdom: a bold vision, a nervous Treasury. At his first conference as Prime Minister, Andy Burnham asked for ten years to change the country’s course: a National Care Service “free at the point of use”, electoral reform, greater public control of housing, energy and water, and a review of options for Britain’s relationship with the EU — from the single market and customs union to eventual re-entry. The faithful cheered; the gilt market was less enthused. Thus the Chancellor, John Healey, has insisted that the 28 October Budget will meet the fiscal rules and that the headline rates of income tax, National Insurance and VAT will not rise; tellingly, he has not ruled out increases elsewhere. Meanwhile, Westminster speculates about a snap election as early as May, to escape Starmer’s fiscally restrictive manifesto while Reform UK, battered by scandals, has slipped into second place in the polls. However, the “Burnham bounce” is already fading, with Labour and Reform level in several polls; and Theresa May’s 2017 failed gamble remains the cautionary tale.
France: Mélenchon rides the blockades. In France, Jean-Luc Mélenchon has thrown La France Insoumise behind the high-school blockades spreading from Île-de-France, urging activists to “interpose” themselves between pupils and police and accusing the government of ordering repression. Prime Minister Sébastien Lecornu has retorted that exploiting teenagers’ anger for partisan ends is a fault. The calculation is transparent: the young are LFI’s growth market ahead of the 2027 presidential election. Yet by casting himself as the candidate of disorder, Mélenchon makes himself the ideal run-off opponent for the Rassemblement National — the one scenario in which the “republican front”, which has repeatedly blocked the far right, might simply stay at home. The risk is that, while further increasing his weight on the left part of the political spectrum, he will scare the moderate electorate, making Marine Le Pen looking that the “safer pair of hands”, now that her party has abandoned the anti-euro rhetoric.
Spain: short of votes, long on scandal. In Spain, Pedro Sánchez has again seen Congress reject housing measures meant to define what he billed as “the legislature of housing”. Squeezed between Junts, which demands tax breaks for landlords, and Podemos, which refuses them, his minority government can neither legislate nor pass a budget. An early vote — and Moncloa already argues that any election in 2027 would not count as early — could renew a mandate battered by the corruption scandals surrounding his party and family. Here, though, the moderate veto is exercised less by voters than in Parliament, by a centre-right Catalan party. The risk in that, the Partido Popular of Alberto Feijó and Vox of Santiago Abascal will join forces and oust Sanchez from la Moncloa at the next election, and form a right-wing government, very skewed towards the far right.
Therefore, the common thread is less the left’s revival than its discipline. Burnham’s real constraint is the bond market — the moderate voter’s most unforgiving proxy; Mélenchon’s is the republican front; Sánchez’s is parliamentary arithmetic. History is instructive: Blair in 1997 and Hollande in 2012 won from the centre; Corbyn in 2019 did not. Should today’s leaders overreach, the beneficiaries would be Reform UK, the RN and a PP–Vox alliance — the very forces this leftward revival was meant to contain.
