Will the Minister comment on the inclusion of mobile phones in list B, rather than list A, given the increasing problem of mobile phones being smuggled into prison? They are often concealed, for example, within laptops that are used in the preparation of legal cases. Such smuggling may pose a risk in terms of public threats, including terrorism and other issues; if criminals are able to contact the outside world using mobile phones while they are in prison, that would seem to be quite an important issue to address.
