I thank the hon. Lady for her intervention. When we look at the percentages of properties that are non-decent, it becomes clear that these practices are not limited to the small number of rogue landlords. I will say more about that later.
I note that the hon. Member for Brent North (Barry Gardiner) is in his place today. He and I share the challenge of trying to deal with the many individuals who bought a property many years ago and who, when their lifestyle changes, moved out and chose not to sell their property but to rent it out. Unfortunately, some of those individuals are now exploiting vulnerable people, and they need to be called to account.
In north-west London, we also have a huge number of what are termed “beds in sheds”. These are small developments in back gardens and alongside properties where unscrupulous landlords force people to sleep in absolutely unacceptable conditions. The local authorities attempt to enforce the rules but their resources are limited. As a constituency Member, I routinely draw local authorities’ attention to these landlords, but resources are limited. As the hon. Member for Sheffield South East said, local authorities need resources if they are to enforce the existing laws. I am concerned that, without those resources, the good intentions behind the Bill to give tenants rights and to ensure decent homes may not come to fruition.
