Starmer is expected to submit his resignation to King Charles before Burnham is invited to form a new government. Burnham will then travel to 10 Downing Street to deliver his first speech as Prime Minister. He is expected to begin appointing his cabinet and outlining his government's priorities as Britain faces challenges including slow economic growth, pressure on public finances, and reform of public services.

Burnham, the former mayor of Greater Manchester, won the support of 349 of Labour's 401 lawmakers to become the Party's new leader, paving the way for him to succeed Starmer as Prime Minister.

Under Britain's parliamentary system, the leader of the party with a majority in the House of Commons becomes Prime Minister without a general election. The next general election is expected in 2029.
