The noble and learned Lord is completely right that drones pose a major and serious threat to all our prisons. I have been visiting Manchester prison for over 20 years, and I went there just before Christmas, in the light of the problems that it has. I saw for myself the issues that staff are dealing with, with 49% of the prisoners arriving in the prison being addicted to drugs. I cannot share the counter-drone tactics as that would play into the hands of sophisticated and serious organised criminals. I can assure the noble and learned Lord that we are currently getting on with a number of fixes, but the biggest fix is ensuring there is no market for drugs and weapons in the first place, and that people in prison are there to get on with their sentence, get educated and do purposeful activity, so that when they are out, they stay out.
