# Andy Burnham Set to Become UK Prime Minister After Winning Labour's Backing

Andy Burnham, the former mayor of Greater Manchester, is set to become Britain's next prime minister after winning the overwhelming backing of Labour's members of Parliament. He is not yet formally in office, but is expected to take over from the outgoing government within days, inheriting a weak economy and a divided party.

Andy Burnham, long one of the best-known figures on Britain's political left, is set to become the country's next prime minister after securing the overwhelming support of Labour's members of Parliament. He won 322 of 403 Labour MPs' votes on Thursday, [as reported by U.S. News](https://www.usnews.com/news/world/articles/2026-07-10/andy-burnham-poised-to-become-britains-next-pm-after-most-labour-lawmakers-support-him), all but assuring his path to Downing Street.

## Not quite prime minister yet

Burnham is, for now, the prime-minister-designate rather than the formal holder of the office. Labour is expected to confirm him as its leader in the coming days, after which he would go to King Charles III to be asked to form a government and would then formally become prime minister. The distinction matters: the transfer of power is imminent and, given his margin among MPs, effectively settled, but it has not yet legally taken place.

## How he got here

His rise follows the resignation of Keir Starmer, who stepped down as prime minister and Labour leader after losing the confidence of his MPs in the wake of poor local election results and sliding poll ratings, less than two years after Labour's general election win. Burnham, who had spent years as mayor of Greater Manchester and was not a sitting MP, first had to return to Parliament: he won a by-election in the Makerfield constituency in June, [the Washington Post reported](https://www.washingtonpost.com/world/2026/06/19/andy-burnham-wins-uk-parliament-seat-key-step-bid-oust-prime-minister/), and gave up the mayoralty to do so. That cleared the way for a leadership contest in which he emerged as the commanding favorite.

## The in-tray

The government Burnham is set to inherit is not an easy one. The British economy has been marked by weak growth, stubborn cost-of-living pressures and a heavy debt-interest bill, and forecasters expect only modest expansion this year. He has signaled a distinctive agenda, emphasizing the devolution of power and spending to England's city regions, an area he championed as mayor, alongside a pledge of fiscal discipline: he has said he would not raise the main rates of income tax, national insurance or VAT, and would keep to Labour's rule that day-to-day spending be funded from tax revenue. Reconciling an ambitious reform agenda with those constraints will be an early test.

## A party, and a country, in flux

Burnham also takes over a Labour Party bruised by infighting and a run of departures, and a country that has churned through prime ministers at a rate unseen in generations; he would be the seventh in a decade. His challenge is twofold: to steady his own party after a turbulent stretch, and to convince a weary electorate that a change of leader amounts to more than another turn of the revolving door. For a politician who has spent much of his career on the outside of the top job, looking in, the hardest part may be that expectations now arrive with the office. The formal handover is expected within days; the substantive test begins the moment it does.
