Andy Burnham, the twice-elected mayor of Greater Manchester, has secured a resounding parliamentary byelection win in Makerfield – a result that political analysts say reopens the race for the Labour Party leadership and poses the most serious challenge yet to Keir Starmer’s embattled tenure.
A mandate from the north-west
Burnham, 56, claimed nearly 25,000 votes in the contest, outpacing his nearest rival from Reform UK by a margin of approximately 10,000. The victory hands the former cabinet minister a parliamentary foothold – and a formal route to challenging Starmer for the party’s top job.
To qualify for the leadership ballot, Burnham must now secure the nominations of 20% of Labour MPs – a threshold equivalent to 81 signatures from the parliamentary party. With momentum building behind him, allies believe that target is well within reach.
“A different kind of leadership”
Burnham has not hidden his national ambitions. In recent months, he has openly spoken of offering an alternative to Starmer’s direction, positioning himself as a more devolutionist, socially confident voice for Labour’s urban heartlands. Internal polling shared with party insiders suggests he enjoys strong favourability among rank-and-file members – a crucial factor in any eventual contest.
His government experience adds weight to the bid: under Gordon Brown, Burnham served successively as Secretary of State for Culture, Media and Sport and as Secretary of State for Health. That dual portfolio, he has argued, gives him a rare blend of public-service credibility and cultural reach.
Starmer under pressure after local election rout
The timing of Burnham’s move is no accident. Labour has been plunged into internal turmoil since May’s local elections, in which the party lost control of the Welsh Parliament for the first time and shed nearly 1,500 council seats across England. The results – widely seen as a punishment vote over policy confusion and internal infighting – have fuelled open dissent on the backbenches.
Despite acknowledging the scale of the defeat, Keir Starmer has refused to step down, insisting he retains the confidence of the parliamentary party. But with Burnham now holding a Commons seat and a visible northern power base, the pressure on the current leader is expected to intensify in the coming weeks.
What happens next
All eyes will now turn to Westminster, where Burnham’s team is expected to begin sounding out MPs imminently. Should he secure the required nominations, a leadership challenge could be triggered as early as the autumn – setting the stage for a bitter contest over the soul of the Labour Party, with the north-south divide once again at its heart.
