Burnham's Momentum Grows, So Do the Questions

As Sir Keir Starmer prepares to leave office, attention in Westminster has rapidly shifted toward the politician widely expected to succeed him: Andy Burnham.

Two developments on Monday strengthened the view that Burnham is now the clear favourite to become Labour leader and potentially prime minister within weeks. Starmer formally outlined a timetable for his departure, while Health Secretary Wes Streeting, regarded as Burnham's strongest potential rival, ruled himself out of the contest and endorsed the former Greater Manchester mayor.

The developments have fuelled expectations that Burnham's rise could be swift. If he succeeds Starmer, he would become Britain's fifth prime minister in four years.

Power Shifts in Westminster

Images from Burnham's first days as MP for Makerfield highlighted the changing political landscape. Senior Labour figures gathered around the newly elected MP, while Starmer and his wife were seen in emotional scenes following the announcement of his departure.

Among those attending Burnham's event was Chancellor Rachel Reeves. Her presence prompted fresh speculation about the future shape of a Burnham administration.

Supporters of Reeves argue she has maintained market confidence during a difficult period and could provide continuity at the Treasury. Others believe her close association with Starmer's government makes it unlikely she would remain in the role under new leadership.

Some Labour figures have privately suggested Streeting could replace her, although he has denied being offered the position.

Concerns Beneath the Enthusiasm

Despite the growing momentum behind Burnham, some Labour figures are uneasy about the speed of events.

Burnham was not a parliamentary candidate at the last general election and only returned to Westminster after winning the recent Makerfield by-election. Critics note that he could become prime minister within weeks despite having spent years outside Parliament.

Questions have also resurfaced about his previous leadership bids. Burnham unsuccessfully sought the Labour leadership twice before, losing to Ed Miliband in 2010 and Jeremy Corbyn in 2015.

Yet supporters argue that circumstances have changed dramatically. Burnham is now viewed by many Labour MPs as an electoral winner, particularly after securing victory in a region where Reform UK has recently made significant gains.

While his popularity in Greater Manchester is well established, some within Labour question how well that appeal translates nationally.

Policies Yet to Be Tested

Another concern among MPs is the limited detail Burnham has provided about how he would govern.

During the by-election campaign, he focused largely on local issues. Since Starmer's resignation announcement, Burnham has spoken broadly about the need to deliver economic growth, improve living standards, strengthen public services, expand housing and create opportunities for younger generations.

However, many in the party acknowledge that these goals are widely shared. The greater challenge will be explaining how they can be achieved.

The lack of detailed policy proposals has led some Labour MPs to discuss encouraging Darren Jones to enter the leadership race. While allies suggest such a challenge remains unlikely, they say he has not completely ruled it out.

Foreign Policy and Spending Questions

The next stage of Burnham's political journey is likely to involve far greater scrutiny of his views on national and international issues.

As mayor, he had little reason to speak extensively on foreign policy. A potential premiership would require him to address questions ranging from Britain's relationship with Donald Trump to defence spending and military readiness.

How he would fund increased public spending, whether he would commit additional resources to the armed forces, and how he would balance competing economic priorities are among the many questions now confronting him.

For a politician whose path to Downing Street appears increasingly clear, many Labour MPs believe the public still knows relatively little about how he would govern once he gets there.
