Shift analysis

Labour's Surge Stalls

By Grace Wilson | 24th August 2026

Based on shifts in our poll analysis from 17/08/26 - 24/08/26. 

​

Labour’s rapid rise in the seat projections has slowed this week, with the party losing 6 seats nationally, falling from 284 to 278. Reform has recovered 3 seats, rising to 106, while the Conservatives have gained 2, reaching 117. This is a relatively small movement compared with the changes seen over the past month, but it perhaps marks the beginning of a stabilisation in the political picture. Labour’s post-Burnham surge has slowed, while Reform and the Conservatives are beginning to reclaim some ground.

 

We have seen four Labour seats move back to Reform this week, with Newcastle-under-Lyme, South Shields, Stoke-on-Trent Central and Swansea West all changing hands. Southend West and Leigh have moved from Labour to the Conservatives, while Cowdenbeath and Kirkcaldy has moved to the SNP. Interestingly, this spread of changes suggests that Labour’s recent recovery is not entirely secure. Reform remains particularly strong in parts of the Labour heartlands. The Conservatives, meanwhile, reclaiming Bromsgrove from Reform could be an early sign that their vote is beginning to stabilise after months of being squeezed from the right.

 

The honeymoon period is now also beginning to face its first real tests. Burnham has enjoyed a month of relatively popular measures. Still, the government is moving beyond the easy early days of the new administration and towards the decisions which will determine whether Burnham’s initial popularity can be sustained. This could explain why Labour’s seat total has begun to level off: voters who returned to Labour following Burnham’s arrival are now judging the government on what it actually delivers rather than on the change in leadership.

 

The North Sea could become particularly important in this respect. Burnham is facing a decision over whether to approve the Rosebank and Jackdaw oil and gas fields, with a decision now expected in the coming weeks. This presents Labour with a difficult balancing act between energy security, jobs and traditional industrial voters on one side, and its environmental commitments on the other. A decision to approve drilling could help Labour with voters who want a more pragmatic approach to energy, but risk alienating the progressive voters who have been brought back into the Labour coalition.

 

This is possibly the wider challenge facing Burnham. His appeal has allowed Labour to reconnect with voters who had moved towards Reform, while also making the party more attractive to voters who had previously looked towards the Greens. But maintaining both groups will be difficult when the government begins making genuinely divisive decisions.

 

Perhaps the most important conclusion this week is that Labour’s recovery remains intact, but its momentum has slowed. Burnham has brought Labour back into contention, but the difficult decisions now facing the government will determine whether this becomes a genuine political realignment or simply another short-term movement in Britain’s increasingly volatile politics.
