Prime Minister Sir Keir Starmer is facing growing pressure from his backbenchers to scrap the two-child benefit cap.
But what is the policy? And why is it causing such a ruckus within Labour ranks?
The two-child benefit cap was announced by the Conservatives in 2015 as part of Lord David Cameron and George Osborne's austerity measures.
It meant, while most parents could claim a payment from the government for their first and second child, they couldn't make claims for any further children they had.
The argument from the Tories was it made the system fairer for taxpayers, ensuring households on benefits "face the same financial choices about having children as those supporting themselves solely through work".
But opposition MPs and campaigners said the measure would drag more children into poverty and hit hard up families.
The policy came into force in April 2017, and the current rules mean parents can claim £287.92 for each of their first two children, but no more.
