My hon. Friend is making an excellent speech and some excellent points. One of the findings of the Environmental Audit Committee’s review of sustainability practices in the Ministry of Justice is that contractors are unaware of their obligations. One site of special scientific interest, an important nature area, was being mown by the contractor with no oversight of the environmental sustainability issues at the prison. Does he agree that any new contracts must be managed in-house in order to have control over the future sustainability of the prisons estate?
