Andy Burnham is poised to officially become Britain's next prime minister on Monday, though several procedural steps must occur first. The transition follows the resignation of the previous leader and the completion of the Labour Party's internal selection process.

Over the weekend, Burnham will meet with King Charles III at Buckingham Palace for the formal "kissing of hands" ceremony, where the monarch invites him to form a government. This constitutional ritual marks the official transfer of power.

Cabinet appointments are expected to be announced shortly after, with key positions including Chancellor of the Exchequer, Foreign Secretary, and Home Secretary. Parliament reconvenes later this week for Burnham's first Prime Minister's Questions.
