Andy Burnham’s crushing by‑election win in Makerfield is being cast either as the birth of Britain’s next leader or the start of an internal crisis that could tear Labour – and its claim to stability – apart.

Liberal-leaning outlets frame the contest as a dramatic personal mandate for Burnham and a rebuke to both Nigel Farage and Keir Starmer. The Guardian describes how Burnham took 54–55% of the vote and "secured 6,100 more votes than both Reform and Restore combined," turning Labour from "the unpopular incumbent" into "the vehicle for change" in a seat where Reform had recently dominated local elections.¹ Commentators argue that he has not just shown Labour "can beat Reform" but must now prove his talk of change is a concrete programme rather than "another slogan for power."² Others go further: The Atlantic declares that "Britain has a new prime minister in waiting," portraying Makerfield as a referendum on Starmer’s leadership and Burnham’s ability to defeat the radical right.³

Within this camp, Starmer is depicted as mortally wounded. One analysis says Burnham’s triumph "leaves the prime minister with only two options: fight openly for the Labour leadership, or leave office cleanly," dismissing Starmer’s claim that "Starmerism" beat Reform as "not credible."² Cabinet loyalists, according to reporting, are telling Starmer he must set a timetable to go or risk being forced out, with one source insisting "everyone thinks it is over" and only a "dignified, orderly exit" remains.⁴

Conservative-leaning coverage converges on the same endpoint but with different emphasis. The Washington Examiner notes Burnham’s 54.8% vote share and warns the victory "could spell political doom" for the "immensely unpopular" Starmer, highlighting Burnham’s own words that "Tonight could, just could, be the turning point."⁵ The Washington Times similarly stresses that winning the seat "puts him in a position to challenge embattled Prime Minister Keir Starmer," focusing less on Burnham’s left‑leaning economic pitch and more on Labour’s looming civil war.⁶

Across the spectrum, then, Makerfield is read as a powerful anti‑Starmer signal. The sharper liberal critiques question whether Burnham’s charisma and "King in the North" brand can translate into a nationally coherent, fiscally credible project; conservative voices treat his ascent mainly as evidence of Starmer’s collapse. Both sides, however, agree that the by‑election was less a local contest than an audition for Downing Street – and that Burnham passed it.
