With all eyes on the three-cornered fight between Labour, the Tories and Reform UK, a fourth force is on the move in British politics.

It’s early days, of course, but the Liberal Democrats are suddenly making progress in the polls. The latest YouGov figures have them up two points to 16%, while More in Common has them up four points, also to 16%. Could it be that Ed Davey’s party is poised for a breakthrough? In last year’s general election, the Lib Dems gained 64 seats — their best result in a hundred years. But that was achieved with a vote share of 12.2%, compared to the 11.6% they managed in 2019. So, on this measure, they didn’t do a whole lot better. Rather, the Tories did a whole lot worse.

So why are the Lib Dems suddenly gaining vote share in 2025? The answer may lie across the pond, where the Canadian Liberal Party has mounted a spectacular recovery in the polls. It’s not hard to discern the reason why: Donald Trump. With their country the target of Trump’s boorish behaviour, Canadian voters are rallying around the maple leaf — and swinging back behind a governing party that represents the opposite of everything he stands for.

As shown by Keir Starmer’s trip to the US this week, the British have been more respectfully treated than the Canadians — so far. Nevertheless, Trump’s policy of siding with Russia against Ukraine has caused widespread dismay. Significantly, of our four biggest parties, the Lib Dems were first to clearly align themselves with British public opinion. As Davey said last Sunday: “shame on Trump for his betrayal of Ukraine.”

No prizes for guessing who’s most in tune with British public opinion. But there are also other issues that could benefit the Lib Dems, including Starmer’s decision to slash the aid budget. Then there’s the prospect of defections by centrist Tory MPs if Kemi Badenoch lurches to the Right — or if she’s deposed for not lurching to the Right. So with both Labour and the Conservatives in deep trouble, the Lib Dems seem well placed to hoover up alienated but anti-populist voters.

One obstacle to further success is competition from other Left-of-centre parties, especially the Greens. A progressive pact might make tactical sense, but that would conflict with the centrist vibe that the Lib Dems need to hold on to their Blue Wall constituencies.

Secondly, the grip they have on the formerly Conservative voters they won in 2024 is tenuous. Analysis from James Breckwoldt of Cardiff University shows that these ex-Tories are very different from other Lib Dem voters. A significant 59% of them voted Leave, 48% support the death penalty, and 72% want tougher prison sentences. Trying to hold on to these defectors while attracting progressive voters from Labour won’t be easy.

Finally, even if the Lib Dem leadership can pull off such a feat of ideological acrobatics, there aren’t many Labour/Lib Dem marginals left in Britain. Of the seats won by the Lib Dems, only two had Labour in second place. And of the 411 Labour seats, only six had the Lib Dems in second place.

The irony of winning increased support from the Left is that it could cost the Lib Dems more seats than they’d gain. The party may imagine itself to be floating above the chaotic mess of contemporary British politics. But, in reality, they’re just as tangled up as their rivals.
