As we reported a short while ago, cabinet ministers were instructed to ring around the signatories of an amendment to the government's welfare legislation in a bid to get them to back the cuts rather than tanking the entire bill.
Our political reporter Faye Brown has spoken to three more Labour MPs about the behind-the-scenes efforts of the government to avoid a major humiliation.
Did Treasury underestimate new MPs?
One MP who has signed the amendment told her they've had conversations with ministers and "they're doing everything you'd expect" to quell the rebellion, but was clear he wouldn't characterise it as anything like bullying or dirty tactics.
They said the Treasury has underestimated the fact that many of the 2024 intake came from backgrounds in local government with a determination to fight against austerity, and there's not enough in the welfare package to get people back into work.
Talk of early election 'ridiculous'
Another MP said they'd had a "headmaster's chat" with a senior minister, and added that "they've all been at it".
He described talk of this rebellion triggering an early general election as "ridiculous", but said No 10 "just need to change or delay the vote".
Separately, a third Labour said they'd had a "soft request" from a senior colleague to take their name off the amendment, but "they knew they weren't going to get anywhere".
