I agree @Jojoe
As I see it, if any bebifits are affected it will be legacy bebifits ESA etc and UC. Not PIP/DLA and possibly not attendance allowance.
As Jojoe said the problems the Truss government is having and the alrady U-turns on the mini budget, I neither can see why benifits would not increase with inflation. It’s also worth remembering that so many Tory MP’s were agaisn’t it from the start. The mini budget alone caused friction with the IMF and leaders around the world, including the BoE.
