Welfare Reform Bill

I am sorry to come back to this but there are still some unanswered questions. I do not think the noble Lord dealt with the definition of ““in-work”” and when the cap will apply. Is the threshold set at 16 hours, as it is for working tax credit at the moment? How will that change from April? I think for couples there is a joint requirement for 24 hours a week, rather than 16. How will that all work?
