Immigration Bill

Can I come back to single rooms that are let in a house? I have said to the Minister that I am perfectly happy to go along with him if I could know that we have looked at this particular issue. As far as I understand, we have not got very much evidence about the interaction between this legislation and people letting rooms in their own house. Do we know how many people have been interviewed on this? Do we know that it does not have the effect that I fear it has? If he can show that to me I will withdraw entirely but I just want to know and I am not sure that the evidence is there.
