Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what assessment he has made of the potential impact of staff shortages in offender management units on errors in calculating prisoners release dates.

Releases in error have been increasing for several years and are another symptom of the prison system crisis inherited by this Government. The safety of the public is our absolute priority.

While the overwhelming majority of offenders are released correctly, any release in error is treated with utmost seriousness and we are clamping down on those that do occur. On 11 November, the Deputy Prime Minister announced a five-point action plan setting out initial steps to address this issue. As soon as an error is identified, we immediately assess the individual’s risk and work closely with the police to ensure swift action. A joint protocol between HMPPS and NPCC is in place, to ensure effective and timely communication between partner agencies when an individual is released in error to rearrest them as quickly as possible.

Totals for releases in error are published each July in the HMPPS Annual Digest, with the latest available via HMPPS Annual Digest, April 2024 to March 2025 - GOV.UK, which provides data up to March 2025. These include information on the principal offence group of those released.

A further transparency ad hoc publication, available via Releases_in_Error_from_1_April_2025_to_31_October_2025.pdf, also covers the number of releases in error from 1 April 2025 to 31 October 2025. Further breakdowns of this data cannot be provided at this time because they would give an early indication of future Official Statistics.

Offender Management Units play a vital role in our prisons, including processing prisoner releases. Prisons are encouraged to fill vacancies promptly, with the Department providing support on best practice in recruitment. We are also rolling out technology-based upgrades to assist frontline staff, helping to reduce human error.

The Government is determined to fix the issue of mistaken releases and ensure the public is properly protected.
