On Thursday 3 July 2026, Andy Burnham sat down at his computer and began answering questions from thousands of Reddit users. Within two weeks, he is expected to become prime minister without a single vote being cast. Burnham, the newly elected MP for Makerfield, is the sole candidate to replace Sir Keir Starmer as Labour leader and will likely enter Downing Street on 20 July. The last general election was held on 4 July 2024, when Labour won a landslide. Under the Fixed-term Parliaments Act, the next election must be held by August 2029, but a prime minister can call one sooner. Burnham has ruled out an early election, saying he will stick to Labour's 2024 manifesto.
How can a prime minister be replaced without a general election? In the UK, the prime minister is not directly elected by the public. Voters elect MPs, and the party that commands a majority in the House of Commons chooses its leader. That leader becomes prime minister. When Sir Keir Starmer resigned last month, Labour began a leadership contest. Burnham became the only candidate, so the contest effectively ended. He will become prime minister on 20 July, assuming the monarch formally appoints him. Conservative leader Kemi Badenoch has criticised Burnham for avoiding press conferences, and Reform UK leader Nigel Farage has called for an early election. But with a large majority, Labour can govern until 2029.
“How Andy Burnham will become PM without a general election”
Burnham inherits a difficult economic situation. The Guardian reports that Chancellor Rachel Reeves left £23.6bn of fiscal headroom in her March 2026 spring statement. Since then, the Iran war has hit the UK economy, government borrowing costs have risen, and Starmer announced £15bn in additional defence spending over four years. Only £10.3bn of this is funded by reallocating budgets; £4.7bn still needs to be found in the autumn budget. Burnham has committed to Labour's fiscal rules, which require day-to-day spending to be balanced by receipts within five years. The Office for Budget Responsibility will assess whether the books add up. If not, tax rises or spending cuts may be needed.
One policy Burnham has confirmed he will keep is the pension triple lock. Introduced by the Conservative-Lib Dem coalition, the triple lock guarantees the state pension rises each year by the highest of inflation, average wage growth, or 2.5%. Critics say it is expensive and unsustainable, but Burnham told a Reddit user he would not scrap it because the 2024 manifesto committed to it. Some of his own advisers have argued against the triple lock, but Burnham appears to be listening to the manifesto, not the advisers. On Europe, Burnham has promised to work for a closer relationship with the EU, though he has said he will not re-run the Brexit arguments. During the Makerfield by-election he pledged not to reopen that debate. He has also said he would seek returns agreements for failed asylum seekers, including with Taliban-run Afghanistan.
Q: How can the UK get a new prime minister without a general election? A: The governing party can choose a new leader at any time. That leader then becomes prime minister, provided their party still commands a majority in the Commons. The next election does not need to be called until August 2029, so there is no legal requirement for a public vote.
Q: What is the pension triple lock and why is it controversial? A: The triple lock ensures the state pension increases each year by inflation, average earnings, or 2.5% – whichever is highest. It is popular among pensioners but expensive for younger taxpayers. Some economists argue it should be reformed to reduce pressure on public finances.
Q: What fiscal rules has Andy Burnham vowed to follow? A: He has pledged to stick to the rules set by Chancellor Rachel Reeves: day-to-day spending must be balanced by tax receipts within five years. These rules limit his ability to borrow for spending, though he can still invest if the numbers add up.
What happens next? Burnham will be confirmed as Labour leader and become prime minister on 20 July. His first major test will be the autumn budget, where he must find £1.2bn a year for defence and decide whether to raise taxes. The Bank of England and bond markets will be watching closely. If Burnham sticks to his manifesto promises, the triple lock will remain, but the fiscal headroom may be tight. For now, the UK is set for a new prime minister – and no election in sight.
