Keir Starmer has finally bowed to intense pressure to stand down as British prime minister as he conceded that he was no longer the right man to lead the country, leaving Andy Burnham all but certain to succeed him.

In an extraordinary day at Westminster, Starmer announced a timetable for his departure after months of growing discontent among Labour MPs and cabinet ministers, many unnerved by the threat from Reform UK before the next general election.

As the newly elected MP for Makerfield made his way down by train to Westminster, it became increasingly likely Burnham would be crowned Labour leader without having to face a contest, giving him just over three weeks to prepare for government.

After Wes Streeting confirmed he would not challenge him for the top job, the focus among jubilant Labour MPs turned to Burnham’s policy agenda, his plans to take on Nigel Farage’s party and who might be in his first cabinet.
