Is that meant to be a joke?
Even with this bill, spending on disability benefits is due to rise massively between now and the end of this parliament after rising massively since COVID. It doesn't free up any money.
Despite Starmer responding to questions earlier saying they are pushing ahead, I can't see them letting this vote happen if they can't win it comfortably with government votes. Optically they are better off pulling the bill than relying on Tory support.
