Sir Keir Starmer is considering making a humiliating u-turn over planned cuts to disability benefits which have led to the biggest Labour rebellion since he became Prime Minister.
Backing down over measures to cut the number of people eligible for Personal Independence Payment (PIP), which helps disabled people with living costs, would be a massive blow as it would be clear that Sir Keir had been forced to abandon a policy he supports.
But pressing ahead with a planned vote on July 1 only to lose it would be even more damaging. The rebellion against the measure has continued to grow, with at least 123 Labour MPs now signed up to a Commons amendment opposing the measure - enough for the Government to lose the vote unless the rebels back down, and there is no sign of them doing so.
The row is likely to feature in Prime Minister's Questions today, when Deputy Prime Minister Angela Rayner is standing in for Sir Keir, who is attending a NATO summit at the Hague.
The Personal Independence Payment cuts would mean 800,000 people lose an average of £4,500 annually and this would lead to an extra 250,000 people in poverty, including 50,00 children.
But if Sir Keir does perform a u-turn, it will leave a £4.1 billion black hole in the Treasury's finances, as that's how much the changes would have saved. When other benefit cuts are included, the total savings were due to be £5 billion.
