Andy Burnham has called on Sir Keir Starmer to scrap the two-child benefit cap, becoming the latest high profile Labour figure to call on the prime minister to change the policy, amid growing pressure from Labour MPs.
In the clearest sign yet that the Greater Manchester mayor is considering a return to Westminster to challenge the prime minister for the leadership, he said the benefit cap is “arbitrary” and could not be justified.
He described the policy as “the worst of Westminster” and said he “never supported it”.
“It can’t be defended, because it’s arbitrary,” he said. “Why does the third kid just get cut out or get less, or why do all three if you’ve got three kids?”
The intervention will be seen as a direct challenge to Sir Keir on the eve of Labour conference, with questions swirling about the beleaguered prime minister’s future.
It came as Scottish Labour leader Anas Sarwar – who has been an outspoken ally of Sir Keir since he took over as leader – refused to say he has full confidence in the prime minister.
Mr Burnham’s intervention will pile further pressure on the chancellor to scrap the benefit cap long blamed for keeping children in poverty, after more than 100 Labour MPs signed a letter to Rachel Reeves urging her to scrap the limit as she prepares for the autumn Budget.
Meanwhile, the child poverty task force – a body set up by the government to examine the best ways to tackle the issue – is expected to recommend lifting the cap after concluding it is the best way to alleviate the problem.
The recommendation will put the government in a difficult position as they are already understood to be braced for a £20-30bn black hole at the next budget, a sum that would only be exacerbated by the £3bn per year it is expected to cost to lift the cap.
Dame Meg Hillier, chair of the Treasury select committee, told The Independent lifting the cap would be the “quickest and surest way to lift children out of poverty”.
“As well as the challenges – including hunger and humiliation – these children face we have a brith rate of only 1.41 in England and Wales and need to invest in our young people.
“I’ve crunched the numbers and this is the measure that will help the most children the quickest”, she said.
A senior Labour source warned that politically the government has “no option but to lift it”, warning that the view of the parliamentary Labour party is “very clear.”
“I think the government is aware of this”, they added. “[The two child benefit cap] is the only measure that starts turning child poverty around at the scale required”.
Kate Osborne, Labour MP for Jarrow and Gateshead East, told The Independent: “The fact that the two child limit on benefits is still in place is frankly a stain on our government.”
“Scrapping the two child limit is essential – we must undo the damage the Conservatives caused with this cruel and unjust policy that has now pushed more than 4 Million kids into poverty.”
Saying that around two in three children in her Jarrow constituency are growing up in poverty, Ms Osborne warned: “It is unsustainable for the prime minister to ignore the calls from hundreds of organisations, coalitions, task forces and the more than 100 Labour MPs who are asking him to announce its immediate withdrawal without waiting for the budget.”
Ian Lavery, MP for Blyth and Ashington, added that child poverty is “the scourge of a modern wealthy society”, saying it is the “shame of our nation… that our kids are suffering on a huge scale.”
“As politicians we should hang our heads in shame that we understand the magnitude of poverty but choose not to deal with it”, he said.
And Rachael Maskell, who has long campaigned for the cap to be lifted, said that addressing the causes of child poverty is “exactly the step a government must take if it is to end the social injustices in our society”.
“I look forward to reading of all the other measures Labour will introduce, having fed into the consultation, to ensure that child poverty is consigned to the history books in our country”, she added.
The cap, imposed by Tory former chancellor George Osborne, prevents parents from claiming benefits for any third or subsequent child born after April 2017.
The growing pressure on the government comes after Mr Burnham said Labour MPs are privately urging him to challenge the prime minister for the Labour leadership. He accused Downing Street of creating a “climate of fear” and said “wholesale change” was needed to see off the “existential” threat of Nigel Farage’s Reform UK.
Mr Burnham, who is one of three children and whose mother received child benefit, told The Guardian: “My parents always said to me something that has definitely guided me in my life – you can never visit the sins of the parents on the kids.
“It’s just a ridiculous thing that the state is kind of making these sort of judgmental interventions into families’ lives and saying, ‘Yes, it’s OK for some kids to have a lower standard of living’, because that is family decisions that their parents took, is absolutely abhorrent.
“It cannot be justified. It’s the worst of Westminster, that’s what it is.”
The issue has also been central to the contest to succeed Angela Rayner as deputy leader, with both candidates Bridget Phillipson and Lucy Powell suggesting the limit should be abolished.
Ms Phillipson’s comment that scrapping the “spiteful” cap is “on the table” has been seen as a clear sign that ministers are considering the move.
Ms Reeves on Monday also said the changes were “on the table”, but would not commit to it ahead of the budget.
Asked whether he has full confidence in the prime minister, Mr Sarwar said: “He has got a really difficult job, we have made significant progress in the last year,” he said.
“If I’ve got one single biggest criticism of a UK Labour Government, it is there have been huge successes, but very few people have been told about them or know about them.”
