The Labour Party is united behind Andy Burnham as its next leader, two senior party figures have told the BBC.

The party set out a timeline for a leadership contest following Prime Minister Sir Keir Starmer's resignation earlier this week, but there is scant evidence of support for any contenders other than Burnham.

Former defence minister Al Carns has said a speech on Monday, in which Burnham will set out his economic policy, will decide whether he challenges him for the Labour leadership.

Labour deputy leader Lucy Powell and Housing Secretary Steve Reed, who had stayed loyal to Sir Keir, both said that Labour MPs were backing a coronation of Burnham, rather than a contest.

"I'm pleased that actually what it looks like is we're probably going to have just the one candidate in Andy Burnham," Powell told the BBC's Sunday with Laura Kuenssberg programme.

"How refreshing that would be - that the whole Labour Party is agreed on the new leader and we don't have to go through a contest that could be damaging at this point in time.

"Now we've all got to get behind that leader and stop the kind of infighting and chitter chatter from the background."

Reed agreed the party was "going to move very swiftly to uniting behind Andy Burnham" without "turning inwards", which he described as absolutely essential.

While a general election is not necessary to replace a prime minister, calling one is seen as a test of a new prime minister's support among the public.

Powell was among then-opposition figures to call for a general election when the Conservatives forced Liz Truss out of office as prime minister in 2022.

But she denied that it was hypocritical that she did not want one to test a new Labour leader.

"I think we were in very particular times after Liz Truss crashed the economy," she said, adding: "People want us to get on with the job and deliver the change they want to see."

Reed, too, said this time was very different as the Tories had repeatedly changed leader while in government.

He said he was backing Burnham, but insisted Labour owed a debt of gratitude to Sir Keir.
