Keir Starmer’s landslide win fades as public support collapses

Keir Starmer inherited a Commons supermajority, but not the kind of political mandate that can survive disappointment. Labour’s 2024 victory delivered 411 seats on just 33.7% of the vote, while the Conservatives crashed to 121 seats and 23.7%, a result built as much on Tory collapse as on a sweeping Labour surge.

That gap matters because the first year in power exposed how thin the public coalition behind Starmer really was. By October 2024, Ipsos found only 13% were satisfied with the way he was doing his job as prime minister, while 79% were dissatisfied, the worst satisfaction score it had recorded for any prime minister since 1977. By February 2025, 56% of the public said they were disappointed in what Labour had done so far.

The slide continued into June 2025, when Ipsos said Labour’s voting intention had fallen to 25%, its lowest reading since October 2019. At the same point, 73% said they were dissatisfied with Starmer and 76% were dissatisfied with the government. By 2026, Ipsos found that 50% of Britons thought Starmer should stand down as prime minister and Labour leader. A landslide in seats had turned into a hard lesson in how quickly a shallow victory can be squandered.

The warning is sharper when measured against Labour’s own history. BBC coverage noted that Starmer’s win fell short of Tony Blair’s 1997 majority in popular-strength terms, and that Labour’s national vote share had risen by only 2 percentage points. The party did not so much storm the country as inherit the wreckage of a collapsed Conservative machine. That left Starmer with power in Westminster, but far less durable authority in the country.

For Democrats and other center-left parties watching across the Atlantic, the lesson is plain. A lopsided electoral map can disguise a fragile mandate if the opposition implodes and the winner enters office without a broad, enthusiastic base. Starmer’s trajectory shows how quickly a huge parliamentary majority can look like an empty one if voters do not feel immediate improvement and if the original frustration that drove the opposition’s collapse is left untouched.
