To ask the Secretary of State for Justice how many (a) probation staff and (b) staff work for the Interventions and Substance Misuse Department. (280830)

Of 157 staff currently in post in the National Offender Management Service's Interventions and Substance Misuse Group 10 are probation staff.

Prior to the NOMS Agency being formed in 2008, the Prison Service tended to manage interventions centrally whereas the probation service managed interventions regionally. Hence ISMG, being a central headquarters function, has largely been formed from existing groups that were previously part of HM Prison Service.
