Andy Burnham is set to be announced as the Labour Party's new leader on Friday.
The Makerfield MP is scheduled to be unveiled at a special press conference before taking over as the UK's seventh prime minister in a decade on Monday.
Burnham is expected to deliver a speech during the conference where he will reportedly pledge to be "unashamedly Labour" and vow that his government will have the "courage to fix the big things that politics has neglected."
Burnham was left with a clear path to Downing Street after his last potential leadership rival ruled out challenging last week. He received 379 nominations from Labour MPs for the party leadership out of a possible 403.
His uncontested run has sparked concern from some analysts and government insiders, however, and opposition leader Kemi Badenoch has accused Labour of "running scared" of scrutiny.
