Andy Burnham confirmed as Labour leader, set to become UK's seventh prime minister in a decade on Monday

Andy Burnham was formally proclaimed leader of the British Labour Party on Friday, clearing the last procedural hurdle before he replaces Keir Starmer as prime minister on Monday. The 56-year-old former mayor of Greater Manchester secured the backing of 379 of the party's 403 MPs, making him the sole candidate and turning the leadership contest into a formality.

A coronation without contest

Burnham's path to the leadership was sealed on Wednesday when he surpassed the 81-MP threshold with 379 endorsements, mathematically ruling out any rival. The former defence minister Al Carns, who had considered standing, confirmed he would not run and gave Burnham his public support. By Thursday's nomination deadline, Burnham had also won the backing of at least three affiliated organisations, including the trade unions Unite, Unison and ASLEF, the last of which represents 1.3 million public service workers.

Under Keir Starmer's leadership, we went from our worst defeat to one of the best victories in our history. He put the Labour Party back in a position to change people's lives, and that is what we have been doing these last two years.

The special party conference on Friday was a mere confirmation of the outcome. Burnham, who had failed to win the leadership in 2010 and 2015, joked earlier this month: "Hopefully third time lucky."

Starmer's swift downfall

Starmer's resignation, announced on 22 June, followed a punishing set of local and regional elections on 7 May in which Labour lost more than 1,400 councillors. The defeats, combined with the resignations of his defence and health ministers and the controversy over the appointment of Peter Mandelson as ambassador to Washington (Mandelson had a close relationship with the late convicted sex offender Jeffrey Epstein), eroded his authority beyond repair.

It is the end of my political career.

Starmer will travel to Buckingham Palace on Monday morning to tender his resignation to King Charles III. The monarch will then receive Burnham and invite him to form a government. No general election is required; Labour retains the majority it won in July 2024, and the next national vote is not due until 2029.

The 'King of the North' and his agenda

Burnham, often called the "King of the North" for his decade-long tenure as mayor of Greater Manchester, has promised an "unequivocally Labour" government. He has criticised the centralisation and privatisation of the 1980s and pledged to build an economy "that works for everyone." His plans include moving some government institutions from London to Manchester, increasing council budgets, and making social care a priority.

I am ready to lead and build on the foundations laid.

On immigration, Burnham has signalled he will maintain restrictive policies, and he has not indicated any acceleration of Starmer's cautious rapprochement with the European Union.

What happens next

Burnham will become the seventh British prime minister since 2016, a list that includes David Cameron, Theresa May, Boris Johnson, Liz Truss, Rishi Sunak and Keir Starmer. All six transitions occurred without a general election, a pattern that has marked British politics since the Brexit referendum.

On Monday, after the formal audience with the King, Burnham will travel to 10 Downing Street to deliver his first speech as prime minister and begin announcing his cabinet. His immediate challenge is to halt the rise of the right-wing Reform UK party and restore public trust in a government that has seen seven leaders in a decade.
