Sir Keir Starmer has announced his resignation as Labour Party leader, creating a vacancy that will lead to a contest to select a new prime minister. Starmer, speaking from Downing Street, stated that he does not believe he is the best person to lead Labour into the upcoming general election.

He has formally informed the King of his decision to step down. The Labour Party's governing body has been asked to establish a timetable for the leadership contest. Nominations for the position are set to open on July 9 and will close by the summer recess on July 16. Starmer indicated that a new leader would be in place before Parliament reconvenes in September.

Starmer pledged to remain as Prime Minister until the leadership contest concludes, ensuring an orderly transition of power. He also committed to offering his successor "full and unequivocal support," expressing confidence that they would inherit a stronger and fairer Britain than the one he took over two years ago.

Andy Burnham is currently considered a leading candidate to succeed Starmer. His prospects received a significant boost following his decisive victory in the recent Makerfield by-election against his Reform UK opponent. Burnham confirmed on Monday his intention to stand in the leadership contest.

Former Health Secretary Wes Streeting, who was previously seen as a potential rival to Burnham, has publicly endorsed the former Greater Manchester mayor. This backing strengthens Burnham's position within the party as the contest approaches.

Other potential contenders are still assessing their options. Former Armed Forces Minister Al Carns stated that he has not yet made a decision about whether he will run for leadership. The coming weeks are expected to see further declarations and shifts in the leadership landscape.

Upon arriving at Euston station, Burnham acknowledged Sir Keir's dedication and service to the party. When questioned about potentially calling a general election if he becomes Prime Minister, Burnham stated that such considerations were premature, with his immediate priority being sworn in as the Member of Parliament for Makerfield.

Following his formal swearing-in as an MP in the House of Commons, Burnham was met with cheers from Labour members and some interjections from the opposition. He then joined approximately 200 Labour MPs for a group photograph in Westminster Hall. Burnham is expected to deliver a speech next week outlining his vision for growing the party.
