Andy Burnham's Victory Paves the Way for Labour Leadership Challenge
Burnham's Significant Win in Makerfield
Andy Burnham, the mayor of Greater Manchester, has successfully navigated the first step in what could be a serious attempt to succeed Keir Starmer as the leader of the Labour Party. This week, he secured a parliamentary seat, creating a viable route to challenge for leadership and potentially the role of Prime Minister. Interestingly, Starmer had previously supported Burnham's unsuccessful bid for the Labour leadership in 2015.
A Strong Performance in Makerfield
Burnham triumphed in a by-election for the Makerfield constituency in northwestern England, achieving a notable 54.8% of the vote. His closest competitor, Robert Kenyon from Nigel Farage's Reform UK, garnered 34.5%, while a third party, Restore Britain, received less than 7%.

This victory is significant, especially considering that just six weeks prior, Reform UK had made substantial gains in local council elections in the same region. Burnham's decisive win strengthens his argument that he is better positioned than Starmer to reclaim voters who have shifted towards Farage's party.
Starmer's Response and Leadership Challenges
In the wake of Burnham's victory, Starmer reaffirmed his commitment to his position, stating he would not resign if challenged. He expressed, "If there is one, I'll stand. I'm not going to walk away."
Burnham's success was not entirely unexpected, as Starmer's leadership had been under scrutiny for several months. A series of missteps, unpopular decisions, and disappointing local election outcomes had led nearly 25% of Labour MPs to call for his resignation.
Starmer's approval ratings have plummeted, marking the lowest satisfaction levels for a British Prime Minister in fifty years. His policies, including tax hikes and spending cuts, have alienated traditional Labour supporters. A notable controversy arose when Starmer appointed Peter Mandelson as ambassador to the US, which backfired due to Mandelson's connections with Jeffrey Epstein, leading to his dismissal and raising questions about Starmer's judgment.
These developments occur amid a broader shift in British politics, with local elections showing a trend towards insurgent parties like Reform and the Greens, and nationalist parties gaining traction in Wales and Scotland. Many Labour MPs fear losing their seats unless a leader emerges who can better connect with the electorate. Additionally, Starmer's past actions in ousting former leader Jeremy Corbyn continue to haunt him among the party's left wing.
Navigating the Leadership Challenge Process
Burnham's election to Parliament is just the beginning. Starmer has made it clear he will not resign voluntarily, so for Burnham to mount a formal challenge, he must navigate Labour's internal rules. This includes securing nominations from 20% of Labour MPs, which equates to 81 MPs. It appears Burnham has already achieved this level of support.
Additionally, he needs backing from 5% of local Labour constituency parties or support from at least three affiliated organizations, including two trade unions. Starmer would automatically be included on the ballot unless he opts to step aside.
A Unique Political Moment
This situation is unprecedented; no Labour Prime Minister has faced a formal challenge from their own MPs while in office since Ramsay MacDonald in 1924. The only contested leadership election during a government term occurred in 1976, triggered by Harold Wilson's resignation.
Some Labour leaders have chosen to resign under pressure rather than face a challenge, as Tony Blair did in 2007. However, forcing a sitting Prime Minister out through a direct challenge would be a first in the party's history. This context has led some of Burnham's supporters to lobby Starmer's cabinet members, hoping to persuade him to resign voluntarily, which could allow Burnham to run unopposed.
Potential Contenders for Leadership
Burnham is not the only potential candidate if a leadership contest occurs. Wes Streeting, the former health secretary from Labour's center-right, has expressed his intention to run. Additionally, former deputy prime minister Angela Rayner, who has significant support from the party's left, is also a possible contender.
Other names being considered include Home Secretary Shabana Mahmood, former armed forces minister Al Carns, and former Defense Secretary John Healey.
Deciding the Leadership Election
If a full leadership election takes place, the decision will not rest solely with MPs. Grassroots Labour members and affiliated supporters, including union members, will cast the final votes. To participate, voters must have been members for at least six months before the voting schedule is announced. Each voter ranks candidates by preference, and if no candidate secures over half of the first preference votes, the lowest candidate is eliminated, and their votes are redistributed until someone achieves the required threshold.
Interestingly, Labour's membership has declined under Starmer, dropping from around 330,000 to fewer than 250,000, which may actually benefit him in any vote, as those remaining are generally more likely to support the status quo.
