Question to the Ministry of Justice:

To ask His Majesty's Government what sentences have been imposed to date on ISIS members convicted in the UK; how many of those convicted are still serving their sentences and what steps they have taken to ensure that ISIS members convicted in the UK do not pose any continuing threat to their victims or society.

The Ministry of Justice publishes data on the number of convictions across England and Wales for a wide range of offences in the Outcomes by Offences data tool available at: Criminal justice statistics - GOV.UK.

However, data centrally held does not contain information on specific terrorist organisation affiliation.

Data published by the Home Office in relation to the operation of police powers under TACT 2000, shows that, as of 31 December 2025, there were 267 prisoners in custody for terrorism or terrorism‑connected offences in England and Wales. Of these, 58% (155) were assessed as holding an Islamist ideology, 29% (77) an Extreme Right‑Wing ideology, and 13% (35) were categorised as holding other ideologies.

The Government takes robust action to manage the risks posed by terrorist offenders. In custody, the most dangerous and influential radicalisers can be held in Separation Centres, away from the mainstream prison population, while Close Supervision Centres are used to manage the most physically violent prisoners. Upon release, terrorists are subject to strict licence conditions which severely limit their activity. These can include extended periods of electronic monitoring, accommodation in Approved Premises and polygraph testing. HMPPS, Counter Terrorism Policing and the Security Service work jointly to manage the risk of terrorism-related releases.
