Dr Julian Lewis: Following what my hon. Friend the Member for Guildford (Mr. St. Aubyn) said about rough sleepers, is the Minister [Hugh Bayley] satisfied that enough is being done to tackle the problem given that, to the untrained eye, there seems to be no obvious diminution in the number of people sleeping rough? During the period of the previous Government, the media made a great deal of rightful protest about that problem, but they are strangely rather silent about it now.
