The right hon. Lady is right to say that confidence is extremely important as far as the day-to-day work of prison officers is concerned. She has been involved with these issues for many years, and she will know that the Prison Service has been affected in a major way by waves of drugs. In the early 1990s, and before that, such things had serious implications on prisons, and led to riots and serious assaults in high numbers. We have a two-year violence reduction project. It would not be helpful now to give the House a shopping list of individual measures, but detailed, serious work is taking place across the estate, including the violence diagnostic tool and many other measures to help back up hard-working prison officers. The body-worn camera initiative is also proving valuable, and we hope to say more about that soon.
