Labour has overtaken Reform UK in national polls for the first time since March 2025. Three separate surveys, all conducted after Andy Burnham became prime minister on July 20, 2026, show Labour either level with or ahead of its right-wing rival, Reform UK. People are already calling it the "Burnham bounce." Reuters reported the shift on July 28, based on polling from More In Common, YouGov, and Sky News.

The numbers are consistent across pollsters, though the exact figures differ. A More In Common poll on July 28 put Labour at 28% and Reform UK at 24%. A Sky News survey had Labour at 30%, ahead of Reform UK at 27%. YouGov's poll for The Times and Sky News, done on 26-27 July, showed both parties tied at 22%, with the Conservatives just behind at 21%. YouGov called it an "effective tie between the three largest parties." The Guardian and the Telegraph both reported the overtake on July 27. The Guardian described it as Labour's first poll lead over Reform in more than a year.

Polls work like a snapshot of public mood. Polling companies ask a sample of people which party they would vote for if an election happened right now. They don't predict the future, but they do give a sense of which way the wind is blowing.

The trend over time matters as much as the latest numbers. YouGov's polling across July shows Labour steadily closing the gap. On 12-13 July, Labour trailed Reform by five points (Reform 24%, Labour 19%). By 22-23 July, the gap was just two points (Reform 23%, Labour 21%). Then came the 22-22 tie on 26-27 July. Opinium's polling tells a similar story: Reform led by seven points in mid-June, by six on 1 July, and by just one point on 15 July. Opinium noted that Reform's score was its lowest since 2024. An earlier Ipsos poll on July 3 still had Reform in the lead at 26%, but found that voters preferred Burnham as prime minister over both Nigel Farage and Kemi Badenoch.

Burnham was elected Labour leader on July 16 and became prime minister four days later. Reuters noted his nickname, the "King of the North," from his time as mayor of Greater Manchester. According to the Guardian's "Today in Focus" podcast, hosted by Lucy Hough with senior political correspondent Peter Walker and published on July 28, Burnham's first two weeks in office brought major announcements on the cost of living and on local education aimed at cutting youth unemployment. The Guardian podcast also reported that a social care announcement is expected soon.

The shift is not all about Burnham. Opinium's polling on 7 July suggested that negative headlines about Reform UK leader Nigel Farage were already hurting Reform's standing before Burnham took office. The Conservatives have also been gaining: they rose from 19% in the 12-13 July YouGov poll to 21% by 26-27 July. Opinium recorded them at 19% on 1 July, their highest since April 2025. In other words, Reform UK's once-large lead was already shrinking from more than one direction.

The bigger picture is that Britain has had seven prime ministers in ten years, and voters seem less loyal to any single party than they have been in a long time. YouGov's "Big Voter Study 2026," published on July 13, looked at whether Reform UK's support would hold up, two years after the 2024 general election. The polling firms' answer: Reform's support is real, but it has stopped growing. Whether the "Burnham bounce" becomes a lasting lead or just the temporary boost that new prime ministers often get will depend on what his government actually delivers, starting with the expected social care announcement. What we know for now is that the gap has closed, that three independent pollsters confirm it, and that the narrowing started before Burnham took office but sped up once he did.
