The former minister for children, Lib Dem MP Sarah Teather, who opposes the cap, said: "A few extra months in their own homes is of course welcome news for my constituents, though it would be more welcome still if it indicated a full-scale rethink.

"This does appear to be chaotic. No one can give any information about the timetable now for implementing the cap. Families will face sudden very substantial reductions in benefits when the cap comes into force. … How on earth is a family, already close to the breadline, supposed to budget when no one can tell them when this is going to happen?"
