On Monday, Andy Burnham will walk into Downing Street as Prime Minister without a single general election vote being cast for him as Labour leader. The former mayor of Greater Manchester takes over from Sir Keir Starmer after winning an uncontested Labour leadership contest, backed by 379 Labour MPs and all 11 affiliated trade unions. But the opposition is already calling his mandate into question, with Reform UK leader Nigel Farage demanding an immediate general election so the country can decide the future. So how does someone become PM without a public vote — and is this normal?
In the UK, the Prime Minister is not directly elected by the public. Instead, the monarch appoints the person who is best placed to command the confidence of the House of Commons — usually the leader of the largest party. When a prime minister resigns (as Sir Keir Starmer is doing), their party chooses a new leader internally. If that party has a majority in the Commons, the new leader is invited by the King to form a government. That is exactly what is happening here. Burnham returned to Parliament just a month ago in a by-election, and after being confirmed as Labour leader at a special conference in London, he will meet King Charles III on Monday and become PM.
“Andy Burnham becomes PM on Monday without a general election — here's how that works and what it means.”
This process has a long history in British politics. The last time a prime minister changed without a general election was in 2022, when Liz Truss replaced Boris Johnson (and then Rishi Sunak replaced Truss). Before that, Gordon Brown took over from Tony Blair in 2007. In each case, the new PM governed until the next election, sometimes for years. The justification is that the party with a Commons majority has the right to choose its own leader, and that leader can then govern until the next scheduled election — or until they decide to call one early. Burnham himself has not yet indicated whether he will seek an early election, but his first speech as leader promised “the biggest change in British politics for 40 years”, including devolution and a rejection of “neoliberal” policies.
For UK readers, this matters practically because the policies of the new government will affect everything from social care to the economy. Burnham has promised reforms to social care, devolution of power away from Westminster, and reindustrialisation. But his cabinet picks will signal his priorities. Key figures like Ed Miliband and Shabana Mahmood are rumoured to be in contention for chancellor, and there is even speculation that David Miliband — a former foreign secretary who has spent 13 years running a refugee charity in the US — could return as foreign secretary. The Lib Dems, led by Sir Ed Davey, have already said they welcome Burnham’s call for collaborative politics and want to see changes to water industry regulation, NHS support, and social care, especially for family carers.
Q: Why isn't there a general election when a new prime minister takes over? There is no legal requirement for an election when a PM changes mid-parliament. The UK's uncodified constitution allows the party in power to choose a new leader, who then becomes PM as long as they retain the confidence of the House of Commons. The next election is due by 2029, though the new PM can call one earlier.
Q: What is an uncontested leadership election? An uncontested election happens when only one candidate secures enough nominations from MPs to stand. In this case, Andy Burnham was backed by 379 Labour MPs and all 11 affiliated unions, meaning no other candidate reached the threshold. The result was formally announced at a special conference, with Home Secretary Shabana Mahmood calling it “hardly a nailbiter”.
Q: Can Andy Burnham call a general election immediately? Yes. Under the Fixed-term Parliaments Act 2011 (replaced by the Dissolution and Calling of Parliament Act 2022), the prime minister can request the monarch to dissolve Parliament at any time, triggering a general election. Burnham has not yet said whether he will do so, but opposition parties like Reform UK are demanding one.
What happens next is a flurry of decisions over the weekend as Burnham finalises his cabinet. He has said he will announce his top team on Monday after meeting the King. The composition of that cabinet — especially whether it includes veteran figures like David Miliband or rising stars like Ed Miliband and Shabana Mahmood — will give the clearest signal yet of the direction Burnham’s government will take. Beyond that, his first major tests will be delivering on his promises of social care reform, devolution, and a break from the economic policies of the past four decades.
