You asked
I am looking for budget/real spends on the probation service in years 2010 to 2015.
We said
Thank you for your request.
Unfortunately, we do not hold expenditure data at a level that allows us to separately identify spend by the probation service. We have consulted with statistical colleagues in HM Treasury who inform us that they also do not hold expenditure data at this level of detail. We therefore think you are best placed requesting this data directly from either the Ministry of Justice or HM Prison and Probation Service.
