How many of the prisoners mistakenly released since April 2025 were convicted of violent, sexual or other serious offences; and what assessment he has made of the danger to the public posed by those still at large.

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.

What assessment he has made of the potential implications for his policies of trends in the number of prisoners kept in custody beyond their lawful release dates over the past ten years.

Release inaccuracy is yet another symptom of the prison system crisis inherited by this Government. While the overwhelming majority of offenders are released correctly, we are clamping down on those errors that do occur, and this includes unlawful detentions.On 11 November, the Deputy Prime Minister announced a five-point action plan setting out initial steps which includes an independent inquiry which will report its recommendations to prevent further inaccuracies. The Government is determined to fix release inaccuracies and ensure the public is properly protected.The data requested comes from internal management information and is not centrally collected. It is not quality assured and does not meet the standard required for publication.

What proportion of prisoners tested positive for illegal drugs on arrival and during their time in custody in the latest period for which data is available.

We recognise that the availability and use of drugs in prisons is too high. Tackling this is a priority in order to reduce reoffending, and improve the safety of our prisons. To drive down supply of drugs, we are investing over £40 million in physical security measures this financial year. This builds on the range of specialist equipment prisons already use to intercept contraband, including X-ray body scanners, airport-style Enhanced Gate Security, and baggage scanners.We must also address the demand for drugs which drives this illicit market. We work closely with health partners to identify prisoners with a drug problem and support them into treatment. To create the environment and incentives for prisoners to make the right choices, we have funded Incentivised Substance Free Living Units in 85 prisons. Prisoners on these units sign a behaviour compact, agree to be regularly drug tested and can access enhanced opportunities compared to a standard wing. Alongside this, we are working to increase access to mutual aid fellowships in prison, which can provide vital ongoing support for people in recovery.The information requested regarding the proportion of prisoners testing positive on arrival and during their time in custody can only be provided at disproportionate cost.

How many prisoners were held in custody beyond their lawful release dates in each of the past ten years; and what the total amount of compensation paid was in each year.

What assessment he has made of the potential impact of changes to early release schemes on the accuracy of release date calculations.

On 11 November, the Deputy Prime Minister announced a five-point action plan setting out initial steps to address issues including release in error and unlawful detention. This includes the establishment of an Urgent Warrant Query Unit supported by court experts so prisons can escalate queries to reduce the risk of release in error. We have also stood up a digital rapid response unit to reduce human error with cutting-edge technology. We will provide up to £10 million over the next 6 months to deliver AI and technology-based solutions to support frontline staff, helping to avoid mistakes and calculate sentence accurately. We are also simplifying release policy; one of the aims of the Sentencing Bill is to standardise how cases are treated.

Whether translation (a) cards or (b) services are provided to foreign national prison officers to aid communication with prisoners.

Translation cards or services are not provided to any prison officers working in Public Sector Prisons (PSPs). The process for recruiting prison officers across all PSPs is the same for all applicants, both UK and non-UK nationals, with candidates being appointed to the role based on merit, in line with the fair and open Civil Service recruitment principles. The assessment process for prison officers includes assessments of spoken and written language skills, which will be to the same standard for all candidates, regardless of nationality, and fitness and medical checks.

How many prisoners who have been wrongly released have committed a crime before being brought back to prison in each of the last five years.

This information could only be obtained at disproportionate cost.

What discussions he has had with the (a) Courts and Tribunals Service on ensuring (i) the adequacy of the judicial process for cases involving child sexual abuse and (ii) welfare of child sexual abuse victims and (b) Sentencing Council on ensuring the adequacy of prosecutions for those crimes.

The Ministry of Justice continues to work across Government to strengthen court processes and sentencing, ensuring they are effective and responsive in all cases, including those involving child sexual abuse.HM Courts and Tribunal Service (HMCTS) staff support fair hearings led by independent judges. Special measures are available to enable vulnerable witnesses to give their best evidence, including the option to attend remotely and/or give evidence from witness suites located in court buildings or designated remote sites, designed to provide a supportive environment. Judges also take steps to help child victims feel more at ease, such as meeting them before trial or removing traditional court attire like wigs and gowns. Familiarisation visits can be arranged to help vulnerable witnesses become more comfortable with the court setting and process. Recent reforms include powers to compel offenders to attend sentencing and enhanced training to ensure victims are treated with dignity.We continue to work across Government to ensure victims receive the support they require and need. Victims are supported by Independent Sexual Violence Advisers (ISVAs) during proceedings. The Ministry of Justice funds the CSA Centre to provide training and resources, and invests in specialist services via the Rape and Sexual Abuse Support Fund. Additionally, The Home Office has invested £1.6 million in the Support for Victims and Survivors of Child Sexual Abuse Fund and an extra £1.6 million for national services for adult victims.Charging decisions are a matter for the Crown Prosecution Service. Where an offender pleads guilty to or is convicted of an offence, the independent judiciary determine the appropriate sentence in individual cases within the maximums set by Parliament, and in line with any relevant sentencing guidelines issued by the Sentencing Council.The Sentencing Council has issued a package of guidelines on sexual offences, including child sexual offences. These provide the Court with guidance on factors that should be considered, which may affect the sentence given. They set out the different levels of sentence based on the harm caused and how culpable the offender is. The guidelines also include non-exhaustive lists of aggravating and mitigating factors which can result in an upward or downward adjustment in the sentence.Parliament is responsible for setting the overall sentencing framework and the Government has legislated for strong custodial sentences; through the Crime and Policing Bill, we are introducing measures to make grooming an aggravating factor in sentencing for child sexual offences.
