I welcome my hon. Friend, the new Member for Portsmouth North, to business questions. We had a different Member for Portsmouth North at the Dispatch Box in previous sessions, so I warmly welcome her. She raises an important matter that will be of importance to other hon. Members. Local authorities have planning powers to limit the proliferation of HMOs, but I know from my constituency how difficult those powers are to exercise. She would be well within her rights to raise that with the Deputy Prime Minister, who I think will be in the Chamber before recess to give an update on some of these issues.
