Enforcement is, of course, part of the issue. If we decide that we need to restrict the supply, we will need to have the methodologies of
enforcement. However, I think that I have made it clear that having evidence and information is equally important to underpin any legislative background against which we are operating. There is much going on in this area and I make a commitment to keep noble Lords informed of developments. With that in mind, I hope that the noble Lord will be able to withdraw his amendment.
