Terrorism: Convictions
The question
To ask the Secretary of State for the Home Department, how many individuals convicted of terrorism-related offences are currently present in the UK following completion of their custodial sentences.
Answered by Dan Jarvis
The Home Office does not centrally record the data as requested. However, the department does publish data on the numbers of terrorist offenders released from prison in Great Britain. This includes offenders released at the end of their sentence, as well as those released on licence. This is part of the official statistics publication on the Operation of Police Powers under the Terrorism Acts, which are published quarterly on gov.uk. A total of 41 terrorist prisoners were released from custody in Great Britain in the year ending 30 June 2025.
The UK has one of the strongest counter-terrorism frameworks in the world, including a range of powers to support the management of terrorist offenders upon their release. For example, terrorist offenders can be subject to strict licence conditions and must comply with notification requirements upon release, which allows the police and other authorities to monitor and manage any ongoing risk that they pose.
This legislative framework has been strengthened over recent years and we keep it under continuous review to ensure operational partners have the tools they need to manage the risk posed by terrorist offenders.
