The Labour Party conference, which started on Sunday (September 29), follows weeks of speculation that Greater Manchester’s mayor is preparing to return to Parliament with plans to oust Keir Starmer and become Prime Minister.

During those interviews, the Labour mayor suggested the government should be prepared to borrow more money. Hitting back on LBC this morning (September 29), Ms Reeves said that the mayor ‘risks going the way of Liz Truss’ . Hours later, during her speech, she referred to the former Prime Minister and her disastrous mini-budget in 2022. She said: “Never forget that in two hours one Friday almost exactly three years ago, the Conservatives under Liz Truss sent mortgage costs spiralling. Put pensions in peril. And consigned their party not just to defeat, but to utter irrelevance. “That was a warning. And the British people will not forgive any party that forgets it. “Conference, let us reaffirm our commitment that we will never, ever do what the Conservatives did to ordinary working people in this country. “But I do know that there are still those who peddle the idea that we could just abandon economic responsibility and cast off any constraints on spending. “They are wrong – dangerously so – and we need to be honest about what that choice would mean.” Mr Burnham will only be appearing at a handful of events during the party’s conference this year, the first of which was at a #Labour4PR rally on Sunday (September 28) where speakers made the case to change the voting system. The Greater Manchester mayor, who was dressed in his typically casual attire, was followed by more than a dozen photographers and national broadcasters as he entered the auditorium around 20 minutes after the event started. Photographers were lined up in front of the Labour mayor when he took his seat as cameras flashed furiously. Mr Burnham then delivered a 15-minute speech with no notes in which he started by setting out why he supports a change in the UK’s voting system to proportional representation as well as outlining other changes he wants to see. He insisted that he is ‘here to support the government’ to be successful, but said that he wants to ‘start a debate’.
