We have established specialist teams for prisons that have particular vulnerabilities to drone attacks. I am very happy to meet my hon. Friend to discuss some of the legislative issues. I also believe that there is much more we can do on basic issues such as netting and grills, as well as focusing on high technology.
Drones are one of the ways in which mobile phones are got into prisons, where they can be used for criminality alongside drugs. What measures are being taken to use technology to limit the use of mobile phones in prison?
Two types of technology can be used on mobile telephones. One is jamming technology, and the second, which is more commonly used in prison, is a wand to detect mobile telephones. An astonishing number of phones—at over 20,000, there are far too many—are detected in prisons. We should be addressing this in two ways. The first is by making sure that they do not get in: these are closed environments and we should be able to massively reduce the amount coming in. The second is that, by putting phones in cells to allow people to talk to their families, we can monitor the calls and control the need for phones in the first place.
