My right hon. Friend makes a very important point. I am keen to ensure that we have the innovation that we need, and I have talked about the innovation fund. It is very important that we are led by the data and that where good practice is identified it is disseminated so that it can be taken up elsewhere in the system. That is why it is helpful to have a diversity of supply. Under the old probation trust system, there was a reluctance on the part of many probation trusts to make use of the voluntary and private sectors. We do not want to go back to such a system. None the less a unified model for offender management is a sensible way forward.
