I am not sure I accept that if a premises does not sell alcohol nothing can be done, and I referred earlier to a plethora of powers that are available to the multi-agencies, particularly local authorities. I accept that this is a new issue, and I applaud the collaborative work being undertaken by local authorities, because it is worth them exploring what they can do. The real challenge, however, is enforcement. The hon. Member for City of Durham mentioned the inability of council officers to go around with clipboards enforcing the rules, and the hon. Member for Birmingham, Ladywood identified the issue of protractible roofs, which are rolled open in mid-summer when environmental health officers visit, but closed as soon as they have left. There are certainly challenges regarding the enforcement of existing powers, which is something we should address.
