Andy Burnham, the newly elected MP for Makerfield, is poised to become the UK's next prime minister on 20 July 2026, without calling a general election. In an online Ask Me Anything (AMA) session on Reddit, he ruled out an early election, stating he would stick to the 2024 Labour manifesto. This transition follows Sir Keir Starmer's resignation last month, and Burnham is so far the sole candidate in the Labour leadership race.
The basics are straightforward: Burnham will succeed Starmer as Labour leader and prime minister, but only after a leadership contest that, as of now, has no other candidates. The last general election was held on 4 July 2024, giving Labour a landslide majority. The next election must be called by August 2029, though a prime minister can choose an earlier date. Burnham has confirmed he will not accelerate that timeline.
“Why Andy Burnham is set to become PM without an election, and what his pledges mean for the UK.”
To understand why this is happening, we need to look at the political context. Starmer stepped down after two years in power, citing personal reasons, but insisted his work had stabilised the economy and that Labour should go on to win the next election under Burnham. In his first sit-down interview since announcing his departure, Starmer said he held no personal animosity toward Burnham and would support the new government behind the scenes. This transition is unusual: a sitting prime minister voluntarily resigning mid-term without a snap election, allowing a successor from the same party to take over.
For UK readers, this matters because Burnham inherits a fragile economy. The Guardian reports that the public finances are under pressure from a global energy shock, rising bond yields, and spending demands. Starmer's recent defence investment plan added £15bn in extra spending over four years, with only £10.3bn funded by reallocating budgets — leaving a shortfall of £4.7bn to be found in the autumn budget. The fiscal rules set by Chancellor Rachel Reeves give limited headroom: in March 2026, she had £23.6bn of wiggle room, but the Iran war and rising borrowing costs have likely eroded that buffer. Burnham has committed to no tax rises in line with the 2024 manifesto but may face pressure to consider autumn tax increases.
Key questions answered:
Q: Will Andy Burnham call a general election soon? No. He has ruled out an early election, saying he will work to the 2024 manifesto. The next election is not required until August 2029, though a prime minister can call one earlier.
Q: What are Burnham's key policy pledges? He has promised to stick to the triple lock on pensions, seek a closer relationship with the EU, and negotiate a returns agreement for failed refugees, including with Afghanistan. He also says he will not re-run Brexit arguments.
Q: Is Burnham likely to raise taxes? He has indicated there may be room for movement on tax, but is constrained by the 2024 manifesto and fiscal rules. The Guardian suggests autumn tax rises may be needed to fund his 'new direction'.
What happens next: Burnham is expected to become prime minister on 20 July. He will then face the challenge of funding Starmer's defence commitments while managing strained public finances. The OBR will assess the headroom for spending, and an autumn budget will be crucial. Meanwhile, Conservative leader Kemi Badenoch has called on Burnham to hold a proper press conference and fund the defence shortfall or call an election. Reform UK's Nigel Farage has also demanded an early vote. Burnham's response will shape the first months of his premiership.
