My hon. Friend takes a keen interest in such matters. He is absolutely right to talk about a reduction in violence. Clearly, we need to look maturely and carefully at the overall impact of what has happened in our prisons. It is clear to me that we are working hard in this second wave to ensure purposeful activity and meaningful exercise, as well as more educational opportunities. Looking to get the balance right and ensuring that prisoners feel safe is our No. 1 priority.
