Welfare Reform Bill

I have listened avidly to this debate and been very moved by a lot of it. I also have some experience. I can see that the position is extremely difficult. On the point made by the noble Lord, Lord Patel, about not being able to amend regulations, I should like to ask my noble friend whether you can throw out regulations and put new regulations in their place. I know that we have mixed up concrete and aspic. It is not that regulations are fixed in concrete and cannot be changed—I understand that. However, if we voted saying that the regulations were not appropriate, could we have other regulations?
