I am sorry to press my hon. Friend, but there are two remaining loopholes. The first is that some of these things are not detected by the detection units when the prisoner goes back into prison. Some of these things like BOSS—body orifice security scanner—chairs do not always work, so we cannot always be confident that these things will be found. Furthermore, if in a hospital, a prisoner could take something out and leave it for somebody else to collect outside the prison.
