The “Burnham bounce” has seen Labour take a lead in three national polls – days before the new prime minister is set to crush Reform UK in the first major test of his premiership.

A Survation poll published on Tuesday morning put Labour top with 26 per cent, up one point, with Nigel Farage’s party trailing with 24 per cent, down two points.

It followed More in Common released on Monday which put Labour ahead with 28 per cent compared to Reform’s 24 per cent. A YouGov poll gave both parties 22 per cent on Monday.

The findings show Reform’s dominance of polling – leading in more than 300 consecutive surveys since April 2025 – has come to a shattering end as Mr Farage’s hopes of becoming prime minister appear to be evaporating after Labour’s change of leader.

In another blow for Reform, Labour are eyeing a landslide victory in the Manchester mayor by-election, a contest which was called after Mr Burnham resigned from that position to pave a return to Westminster.

According to polling from More in Common, Labour’s candidate Bev Craig would secure 39 per cent of the vote on Thursday, while Reform expected to gain around 19 per cent. The Greens are currently in third place with 14 per cent, with the Tories on 12 per cent.

In the subsequent run-off, Labour would get around two thirds of the votes against Reform, according to the poll.

When the contest began, Reform were the narrow favourites after the local elections showed they had the highest level of support in Greater Manchester.

Local election results on 7 May in the region gave Reform 30.8 per cent, Labour 23.6 per cent, the Greens 19 per cent and Conservatives 10.4 per cent.

Leading polling expert Lord Hayward told The Independent that the surveys have “changed the discourse of British politics.”

He said: “We are no longer talking about Reform becoming the government – in fact, there is an open question over whether they are the natural party of the right.”

He pointed out that the Tories are in third place in the polls but are now closing the gap on Reform, with Survation putting Kemi Badenoch’s party up two points to 21 per cent.

Lord Hayward added: “There is no doubt there is a Burnham bounce and it has happened quicker than most of us expected.

“Part of it is Andy Burnham himself, his policies and communication and part of it is that Keir Starmer is no longer there.

“That has coincided with a marked decline in support for Reform. They have real problems.”

The peer also noted that Mr Burnham “is using August very well, just as Nigel Farage did last year” with a series of announcements, social media videos and putting Labour on the front foot.

“In contrast, Reform don’t seem to be able to do anything that can halt their decline,” he added.

Mr Farage is currently bogged down in a by-election in Clacton after resigning his seat to trigger a vote. An investigation into a £5 million donation from crypto billionaire Christopher Harbourne is hanging over his head, as well as another into gifts and support he received from convicted money launderer George Cottrell.

None of the major parties are contesting what Ms Badenoch described as “a fake by-election”, leaving 34 fringe opponents – most notably the comedic candidate Count Binface.

But a Reform spokesman insisted that the party is “calm” about the turn in polling.

He said: “We expected Labour to go above us, we are calm about it. Let’s see where everyone is by December.”

In a note on how things can change, the spokesman added: “Two years ago Keir Starmer was flying high in the polls, there were comment pieces talking about him being a sex symbol and the ‘grown ups were back in charge’.”

Meanwhile, Mr Burnham said he would not get “carried away” but was pleased to have “connected with people” after a poll gave Labour its first lead for more than a year.

The prime minister told reporters on a visit to Portsmouth: “I wouldn’t get carried away by any poll. I’m pleased to have made a start where hopefully I’ve connected with people.

“And I am talking a lot about Britain believing again and getting its hope back, and I’m not going to apologise for that. I think we should have a bit more of a spring in our step.”

He added that he would “address some of those big issues this week”, including youth unemployment, social care and housing.
