Prison monitors have criticised overcrowding and a lack of purposeful activity for inmates at HMP Pentonville in north London.
The annual report of the Independent Monitoring Board (IMB) said that the prison population was around 38% higher than it should be and that limited resources for education and industrial training meant that around half the inmates were not spending their time constructively.
It also raised concerns about the impact of future budget cuts, which it fears will have a negative impact on work to reduce reoffending. There have already been reductions in staffing levels at the prison and the report says that further cuts could affect the availability of positive activities such as education and training.
The Chairmain of Pentonville IMB, David Miller, said:
The report did welcome efforts to reduce violence in the prison, and work done to tackle illegal drug usage.
