Andy Burnham has wanted to become prime minister for 16 years but has "used the opportunity in between" to "see Parliament from the outside", according to Liverpool City Region Metro Mayor Steve Rotheram.

Speaking to BBC Breakfast, Rotheram says: "If people believe that Andy Burnham is being made the prime minister so that he can communicate the same message just in a better way or a better form, then they're absolutely deluded."

"Andy wants to go in there and he wants to shake things up."

On the possibility of tax rises, Rotherham says both he and Burnham introduced an additional tax as mayors, saying the "small increase" in Manchester has improved public transport.

"Nobody really complains about a small increase that allows you to do something that’s popular," he says.

It's put to him on BBC Radio 4’s Today programme that some are concerned Burnham does not have a plan, which Rotherham rejects, saying "there's been a plan being worked on for many weeks and months now", and adding "but what you don’t do is you don’t put everything out there in one go".

Andy Burnham will promise a new path for the UK as he becomes Labour leader today.

In his speech at a special party conference in central London, Burnham will argue "Britain took a series of wrong turns in the 1980s" when "political power was centralised and economic power privatised".

As is usual for big set-piece speeches, his team has briefed the media on some of what he will say.

He will say the country needs a "new path to the one we’ve been on for the last 40 years".

Ahead of becoming PM next week, he will pledge to lead a government with the "courage to fix the big things that politics has neglected" and the "conviction to argue for our plans".

Burnham will also promise a "distinctively Labour" approach - with more economic renewal, public control and "reindustrialisation".

He will say his government will be "unashamedly Labour in our priorities and in the decisions we take, putting people and places at the heart of everything we do".

He is also expected to pay tribute to Keir Starmer for taking Labour "from its worst electoral defeat in a century to one of the largest election victories in our history".

He will highlight areas including stronger workers' rights, investment in public services and the Hillsborough Law.

Andy Burnham is moving into No 10 on Monday.

But the beneath-the-radar battle for No 11 Downing St is continuing. Whoever Burnham appoints as chancellor - and next-door neighbour in Downing Street - will send a signal of his intent both to politicians and to the bond markets.

The official line from team Burnham is that no decision has been taken.

Announcements on cabinet posts are not expected to be made until Monday, when Burnham moves to No 10.

Discussions have been taking place among a tight group of people - the next No 10 chief of staff James Purnell, Louise Haigh and the former MP who stood aside for Burnham, Josh Simons.

When Burnham won the subsequent Makerfield by-election the widespread assumption was that the Energy Secretary Ed Miliband would move to the Treasury.

But there has been both noisy and more subtle attempts to influence Burnham's choice of chancellor - ranging from unions with workers in the oil and gas industry and who distrust Miliband's instincts, to Keir Starmer's unpaid 'cost of living' tsar Lord Walker, the boss of Iceland.

I've been told there are "live discussions" over installing Home Secretary Shabana Mahmood in Number 11.

Kemi Badenoch has accused Andy Burnham of "running scared" of scrutiny and warned Labour MPs during Keir Starmer's final PMQs on Wednesday that changing prime minister was not a "silver bullet". However, she has stopped short of calling for a general election.

Ed Davey has also stopped short of calling for an election, arguing that the public will want to give Burnham a chance. TheLiberal Democratleader said if Burnham "is serious about changing the way we do politics", then his "door is open".

Nigel Farage and Reform UK have been highly critical of Burnham and have demanded an immediate general election. Following Burnham's victory in Makerfield last month, the party said the country had "no clue" what he stands for.

Zack Polanski has suggested the Green Party could work cooperatively with Burnham and has urged him to introduce wealth taxes and rent controls.

The SNP says it has "no idea" what Burnham's proposed plan for greater devolution entails, First Minister John Swinney said it showed a "lack of knowledge" about Scotland.

Plaid Cymru's Westminster Leader Liz Saville has urged the next Labour leader to act differently to his predecessors.

At midday, Andy Burnham will be announced as the new Labour leader at a special party conference in central London.

The announcement will come after a short intro by National Executive Committee (NEC) chair and Home Secretary Shabana Mahmood.

For context: As the governing body of the Labour Party, the National Executive Committee provides strategic direction for the party and is made up of representatives from each section of the Party.

From that point on, Burnham is Labour leader.

Keir Starmer will continue to be prime minister, until he goes to see the King on Monday morning to resign. Burnham will then follow him to the Palace to be asked to form a government by the King.

This is a moment shorn of any real capacity for surprise – and, until Monday at least, its logical consequence as well: Andy Burnham actually becoming prime minister. His argument today will be one he’s been rehearsing since at least his by-election campaign launch in a dusty car park near Wigan in May.

“Returning power to communities” as he puts it, and a new path from the one he claims the country has been on “for the last forty years” – a period taking in not just the leadership of Margaret Thatcher and John Major, but Tony Blair, Gordon Brown and their successors.

He’ll say his approach will be “distinctively Labour, unashamedly Labour” – with more “public control” and “reindustrialisation".

He’ll also argue he’s open to working with other parties on the long term issues the country faces. In a video posted on social media last night, he reflected on his own family’s experience of the social care system in England.

“If there’s one area where I’m going to expend quite a lot of political capital, it’s going to be social care,” he said.

Today is the day the Labour Party officially gets its new leader in Andy Burnham.

For the rest of the country, it's one day closer to a new prime minister - on Monday, Burnham will take that position from Keir Starmer, who announced his intention to resign last month.

It has not been entirely straightforward for Burnham - his first attempt to return to Parliament was blocked by Starmer before he ultimately stood in and won the Makerfield by-election.

The former mayor of Greater Manchester effectively won the leadership contest before it even got under way, gathering the support of so many Labour MPs that it was mathematically impossible for anyone else to run against him.

In a speech later, he is expected to set out a new path for the UK with a "distinctively Labour" approach of economic renewal, public control and "reindustrialisation".

Burnham will say that when he is in Downing Street, the government will be "unashamedly Labour in our priorities" and have the "courage to fix the big things that politics has neglected".

We'll bring you the key lines and analysis ahead of Burnham being officially declared Labour leader at a special conference in central London at 12:00 BST.
