My hon. Friend—I will say hon. Friend—has made an interesting point. I understand that local authorities are strapped for cash and have to try to make every penny count, but sometimes it is a false economy when they cut the frequency of collections, because there is more chance of people fly-tipping. I shall go on to that later, but she raises a really good point. Sometimes it is counterproductive to cut back on the number of collections. When the local authority has to collect it later, there is a clear-up cost. If everything was taken in the round, it might be more cost-effective just to collect it in the first place.
