A new support service for the families of prisoners at Gloucester jail has been launched.
The aim is to cut the level of re-offending
The Castle Gate Family Trust will help partners and children through the court process, during sentencing, in custody and in preparation for release.
The prison service said that although other agencies provided similar support through various stages, the trust offered an integral end-to-end service.
The aim is also to help reduce the level of re-offending.
According to prison service figures, 67.4% of ex-offenders are reconvicted within two years of leaving prison and 45% of prisoners lose touch with their families.
Some 150,000 children have a parent in prison and 75% of these children will go on to commit a crime.
About a third of prisoner's children suffer significant mental health problems.
