2026 senior Labour : Blocks Burnham Bid in Risky Manchester Vote

When senior Labour figures gathered at the Titanic Hotel in Liverpool on Friday night, one question dominated the room. Should the party change course, or press on under its current leadership?

That question has only grown sharper after allies of Keir Starmer moved decisively to halt Andy Burnham’s return to Westminster before it had even begun.

There were defensible practical arguments for blocking Burnham from standing in the newly vacant Gorton and Denton seat, not least the scale and cost of the mayoral election that would follow his resignation. Replacing the Greater Manchester mayor would be the largest and most expensive such contest in modern British history.

Yet many Labour MPs, including both Burnham supporters and those otherwise neutral, see the decision less as financial prudence and more as political self preservation. In their view, it was a calculated attempt to shield the prime minister as the party heads toward a daunting electoral test.

A seat with shifting loyalties

Gorton and Denton is a complex and volatile constituency. Home to around 119,000 people, it brings together left leaning young professionals in Levenshulme, white working class Reform voters in Denton, and a substantial Muslim population, around 28 percent, centred on Rusholme and Gorton.

Former Labour minister Andrew Gwynne, who stepped down on health grounds after an extended suspension linked to leaked WhatsApp messages, won the seat in 2024 with a majority of 13,413. Reform UK finished second. While boundary changes mean this is technically a new constituency, it is built from areas that have voted Labour for generations. In Gorton itself, a Labour MP has been returned since the reign of George V.

This time, Reform UK intends to fight the byelection as a referendum on the government and on Starmer personally. National polling averages now put Nigel Farage’s party eight points ahead of Labour, while the prime minister’s personal ratings have fallen sharply since the general election.

From the left, Labour will also face pressure from the Greens and any Gaza focused challenger, whether an independent, a candidate linked to Jeremy Corbyn’s Your Party, or even a revived bid from veteran campaigner George Galloway.

Professor Rob Ford of the University of Manchester said disillusioned Labour voters are likely to peel off in different directions. Nationally, he pointed to the twin rise of Reform and the Greens. Without Burnham’s profile, he expects Labour to struggle, though the result could still be close, shaped by competing local and national forces.

Polling from Britain Elects puts Reform just one point ahead of Labour in Gorton and Denton, though that does not fully capture tactical voting dynamics. Labour hopes fear of a Reform MP will persuade some voters to back Labour at the expense of the Greens and Liberal Democrats, who together secured 17 percent of the vote in 2024.

Ben Walker of Britain Elects estimates that a Burnham candidacy would have added five to seven percentage points to Labour’s vote nationally, enough to put the party four points ahead locally once tactical voting is factored in.

Fallout from the veto

Burnham said he was disappointed after Labour’s national executive committee denied him permission to stand, a requirement for sitting mayors seeking parliamentary selection. The party said the decision was taken to avoid an unnecessary mayoral election that would consume public money and party resources.

Writing on X, Burnham said he had put himself forward to counter what he described as the divisive politics of Reform. He added that the media had been informed of the NEC’s decision before he was, a sign, he suggested, of how the party is now being run.

The decision has infuriated sections of the parliamentary party and risks deepening internal tensions at a time when Labour is already trailing Reform in national polls. One senior Labour source described the move as a gamble on the prime minister’s entire premiership, warning that the party was choosing to fight a very hard byelection without its strongest possible candidate.

The NEC decision was taken by a small group of senior figures, including the prime minister. Sources said the vote was overwhelmingly in favour of blocking Burnham, with deputy leader Lucy Powell among the few to argue he should be allowed to stand.

Supporters of the decision say Burnham is doing an effective job as mayor and that forcing a new mayoral election would cost millions during a cost of living crisis. They also fear Reform could dramatically outspend Labour in the campaign.

Critics dismiss those arguments as a smokescreen. Former shadow chancellor John McDonnell called the move weak and cowardly, warning Starmer that it could accelerate rather than prevent a leadership challenge if Labour loses the seat.

An uphill contest ahead

Timing adds another layer of risk. The government has yet to set a date for the byelection, though it is expected before 7 May, when Labour is braced for losses in devolved elections in Wales and Scotland and in English local councils. Holding the byelection at the same time could bury bad news. Holding it earlier would detach it from the national picture. Neither option is attractive.

Labour will now press ahead with selecting an alternative candidate, with a shortlist to be drawn up by an NEC panel and a vote of local members expected soon.

What is clear is that by blocking Burnham, Labour has chosen to fight in Gorton and Denton without its most popular figure in Greater Manchester. In a seat already pulled in multiple directions, that decision has turned a difficult byelection into an even steeper climb.
