I thank the Minister for an amicable meeting last week about HMP Northumberland. The common denominator throughout the whole prison estate across the country is simply a lack of manpower. That is causing the violence—whether it be prisoner on prisoner or prisoner on staff—mental health issues and the problems with alcohol, “spice” or whatever. The Minister has said that this issue is challenging. What extra measures can he take to ensure that plenty of staff are employed in prisons to maintain a safe environment for everybody on the prison estate?
