Andy Burnham will become the United Kingdom's next prime minister on Monday after winning the Labour leadership following Keir Starmer's resignation.
The former mayor of Greater Manchester is set to become the country's 59th prime minister and the seventh person to occupy 10 Downing Street in the past decade.
The transfer of power will begin after Starmer formally tenders his resignation to King Charles III, who will then invite Burnham to form a government.
Burnham officially becomes prime minister once he accepts the King's invitation before travelling to Downing Street to deliver his first speech and begin appointing his Cabinet.
The change in leadership will be completed within hours under Britain's parliamentary system, where the governing party can replace its leader without holding a general election.
Because Labour retains its majority in the House of Commons following the 2024 election, Burnham automatically becomes prime minister as the party's new leader.
After arriving at Downing Street, he is expected to unveil senior ministerial appointments, with particular attention focused on key Cabinet positions, including the finance portfolio.
Burnham said his government would "lay that path out starting next week" as he pledged to reshape Britain's political direction.
He also said, "It will take us to a country where life is more affordable and all people and places are lifted from where they are now."
Burnham, 56, returns to national leadership after serving as mayor of Greater Manchester, where he became known as the "King of the North" for his advocacy on regional issues.
He takes office facing challenges including sluggish economic growth, high living costs, underperforming public services and struggling utilities.
His administration is expected to move quickly on domestic priorities, with attention focused on taxation, spending, energy policy and the future of underperforming utility companies.
One of the government's earliest decisions was to scrap plans requiring all employees to hold a digital identity document, while Labour figures have also indicated Thames Water could be placed under a Special Administration Regime, bringing the company under temporary government control during restructuring.
Burnham has also pledged to govern for every part of the United Kingdom while seeking to reduce regional inequalities and refocus government resources on improving living standards.
