The Governor and his staff have done some excellent work with the police to challenge gang affiliation in prisons, the chief executive of the National Offender Management Service said, after inspectors warned over high levels of violence. Michael Spurr added:
Isis manages a difficult population of young adult men - many of whom are serving sentences for violence and have links with London gangs.
As the Chief Inspector makes clear, Isis is an improving prison. In particular, it is doing really good work to support resettlement. Three quarters of prisoners go into employment or training on release - this is crucial for successful rehabilitation.
