Question to the Ministry of Justice:
To ask the Secretary of State for Justice, how many prisoners have been convicted of a serious assault on a prison officer in each of the last five years; and what additional sentence those prisoners were given as a result those assaults.
It is not possible to identify the proportion of serious assaults on prison staff that resulted in a criminal conviction in each of the last five years. Detailed information may be held on court record but to be able to identify these cases we would have to access individual court records which would be of disproportionate cost.
