Imagine knocking on doors in a working-class northern town and asking voters to back a candidate whose explicit goal is to fire your boss.
That is exactly the bizarre reality Keir Starmer faces.
The Prime Minister announced he will personally head to the Makerfield by-election to campaign for Andy Burnham. On paper, it sounds like normal party solidarity. In reality, it is one of the most surreal moments in modern British political history.
Everyone in Westminster knows why the Greater Manchester Mayor is standing in Makerfield. He wants Starmer’s job. He isn't giving up a powerful mayoral role just to sit on the backbenches and vote on committee amendments. He needs a seat in the House of Commons to launch a leadership challenge, and Josh Simons' sudden resignation handed him the perfect springboard.
So why is Starmer volunteering to help build his own execution dock? Because in the brutal math of current UK politics, he has no other choice.
The Straight Fight with Reform UK
Starmer tried to frame his decision as a standard defense of Labour values. Speaking to reporters on a visit to Essex, he called the upcoming vote a "straight fight between Labour and Reform." He urged the entire Labour movement to pull together, regardless of "other discussions that are going on."
That is a polite euphemism for the civil war engulfing his party.
Following a brutal mauling in the recent local and devolved elections, Starmer’s authority has evaporated. Wes Streeting resigned from the cabinet to position himself for the future, though he didn't have the numbers to force an immediate coup. Instead, the pressure shifted to Burnham, the "King of the North," who Starmer previously blocked from running in Gorton and Denton. Weakened and cornered, Downing Street had to let Burnham run this time.
But Makerfield is no safe seat anymore.
- Josh Simons won it with a fragile majority of just 5,399 over Reform UK.
- Nigel Farage's party just swept the local council elections across the constituency.
- Private Survation polling suggests Reform would crush any standard Labour candidate by 53% to 27%.
When Burnham steps into the ring, that dynamic changes. The same polling shows Burnham dragging Labour ahead by a razor-thin margin of 45% to 42%. He is the only asset Labour has capable of stopping Farage from planting a flag in Greater Manchester.
If Starmer tried to sabotage Burnham or stayed away, and Reform won the seat, it would mean instant death for Starmer's premiership anyway. A Reform victory in a historic Labour heartland would trigger an immediate, chaotic panic. Starmer has to back the man who wants to replace him, because a defeat to Farage is a far worse immediate alternative.
The Dual Message on the Doorsteps
The optics of this campaign will be fascinatingly awkward. Canvassers will face a visceral anger from voters who have completely fallen out of love with the Starmer government.
For the past two weeks, the Prime Minister has tried to pivot to a narrative of "delivery." He points to the UK's 0.6% GDP growth in the first quarter of the year. He highlights falling NHS waiting lists and a 50% drop in net migration to 171,000. Chancellor Rachel Reeves just launched the "Great British Summer Savings Scheme," slashing VAT to 5% on children's cinema tickets, meals, and theme parks.
But out in the former pit villages of Makerfield, those statistics feel incredibly distant. People want change they can actually see.
This creates a split identity for the campaign. Starmer will turn up to talk about national economic stability and tax-free mileage rates. Burnham will lean heavily on "Brand Burnham"—his localized, semi-autonomous identity built on sorting out Manchester's buses and standing up to Westminster during the pandemic lockdowns.
The implicit message to disgruntled voters is almost comical: Vote Labour, because it's the quickest way to get a new Labour leader.
What Happens Next
The writ for the by-election will be moved shortly, putting the vote somewhere in late June. If you live in Makerfield or want to watch how this plays out, here are the real dynamics to track over the coming weeks.
First, look at how Reform handles Burnham's past positions. He used to advocate for closer ties with Europe, and Reform activists are already preparing to use that against him in a heavily pro-Brexit constituency. Burnham has already started a media blitz to play down his old pro-EU stances, insisting he is not campaigning to rejoin the single market.
Second, watch the body language between Downing Street and the Mayor's team. Burnham’s office publicly welcomed Starmer's offer to campaign, stating that "anyone who wants to embrace Andy's campaign message is welcome." Notice the phrasing there. Starmer is welcome only if he signs up to Burnham's agenda, not the other way around.
Ultimately, Starmer is gambling that economic stability will buy him time. Burnham is gambling that his personal popularity in the north can halt the Reform wave. It is a high-stakes partnership between two men who need each other to survive the month, even if only one of them can survive the year.
