Question to the Ministry of Justice:
To ask the Secretary of State for Justice, how many people were released from prisons in England and Wales (a) before and (b) after their official release date in each of the last five years.
The information requested could only be obtained at disproportionate cost. Figures on all releases in error, where prisoners are wrongly discharged from an establishment or court when they should have remained in custody with no deliberate prisoner involvement in the error, are published as part of the HM Prison and Probation Service Annual Digest.
