When does he become prime minister?
Burnham became Labour leader on Friday - but he will not become prime minister until Monday.
The process will begin with Keir Starmer meeting King Charles to formally offer his resignation as prime minister on Monday.
The King will meet Burnham soon afterwards, when he will ask him to form a government. Once Burnham has accepted, he will officially be the UK's prime minister. Both meetings usually happen at Buckingham Palace.
Burnham will then head to Downing Street, where he is likely to give a speech outside No 10.
How did he get here?
Andy Burham had long had ambitions to be Labour leader - but could only challenge for the top job as a sitting MP. He was given that opportunity when he returned to Parliament a month ago in a by-election.
Other senior Labour figures abandoned their own leadership ambitions and got behind Burnham, along with the overwhelming majority of the party's MPs. It has meant he has become the Labour leader without a contest.
Who could be in his cabinet?
The short answer is – we don't know. Burnham will certainly want to bring in a new team of ministers, but he has kept the identity of them very close to his chest and is likely to spend the weekend making the final decisions.
