The political landscape of the UK has shifted dramatically overnight. Following a landslide victory in the Makerfield by-election, former Greater Manchester Mayor Andy Burnham is heading back to Westminster. With 55% of the vote and a resounding majority of over 9,200 against Reform UK, Burnham’s win wasn’t just a localized victory — it was a declaration of intent. He has secured his parliamentary launchpad, and his target is squarely on Prime Minister Keir Starmer’s residence at Number 10.
But as the dust settles in Makerfield, the most pressing questions in British politics remain: Can Burnham actually unseat a sitting Prime Minister? What are his realistic chances, and what must Starmer do to survive the storm?
Does Burnham Have What It Takes?
If momentum is the currency of politics, Andy Burnham is currently the wealthiest man in Westminster. Securing nearly 25,000 votes, he decisively crushed the right-wing populist surge, proving to a jittery Labour Party that he can win back traditional working-class heartlands that have felt neglected.
He undeniably has the public backing. Recent Ipsos polling shows Burnham doubling Starmer’s popularity, with 25% of British adults preferring him as Prime Minister compared to Starmer’s 12%. Burnham offers a distinct ideological pivot: rejecting trickle-down economics in favor of re-industrialization, regional empowerment, and a “Buy British” approach to public procurement. His charisma and track record of delivering outside the Westminster bubble present a stark contrast to Starmer’s current technocratic struggles.
What Are His Chances?
Burnham’s chances of becoming the UK’s seventh Prime Minister in a decade are exceptionally high, but the path is strictly governed by Labour Party rules.
To trigger a formal leadership contest, Burnham needs the backing of 20% of Labour MPs — exactly 81 colleagues. Sources close to his campaign suggest he already has those numbers locked in. Furthermore, the mood in the cabinet is reportedly mutinous, with several frontbenchers privately conceding that Starmer’s tenure is effectively “over.” If Burnham can capitalize on this internal panic and formalize his 81 backers, his momentum could make his ascent a foregone conclusion.
How Can Keir Starmer Stave Him Off?
Sir Keir Starmer is famously stubborn, and he has already confirmed that if a contest is triggered, he will stand and fight. However, mere defiance won’t be enough. To stave off Burnham, Starmer must execute a flawless and immediate political triage:
- Consolidate the Cabinet: Starmer spent Friday calling ministers to assess his support. He must quickly secure ironclad public loyalty from key figures like Wes Streeting (another potential challenger) and Yvette Cooper to project authority.
- Weaponize the Fear of Chaos: Starmer’s best defense is framing a Burnham challenge as a return to the bitter division that kept Labour out of power for over a decade. He is already urging MPs to “pull together” and avoid plunging the country into chaos.
- Offer Policy Concessions: Starmer needs to co-opt Burnham’s appeal by immediately pivoting toward the regional investment and working-class economic relief that Burnham championed in Greater Manchester.
What Happens Now?
The next few days will define a generation of UK politics. Burnham will take his seat in Westminster next week, and under Labour rules, he must formally resign his Greater Manchester Mayoralty. This will trigger a massive regional election, currently expected on July 30.
Behind closed doors this weekend, Burnham’s team is pushing Starmer for an “orderly transition” — essentially asking the Prime Minister to set a resignation date, perhaps aligning with the September party conference, to allow for a graceful exit and avoid a grueling civil war.
If Starmer refuses to yield, expect the 81 letters to be submitted, plunging the Labour Party into a high-stakes leadership contest. For those watching the markets, the pound, and the future of British governance, the Makerfield result was just the opening salvo. The real battle begins on Monday.
