Question to the Home Office:

To ask Her Majesty’s Government what are the latest figures of how many British Islamists who have fought in Iraq or Syria for Islamic State (1) are believed still to be in those countries, and (2) have returned to the UK; of those who are known to have returned how many (a) have been prosecuted, (b) have received "de-radicalisation" treatment, and (c) had no action taken against them.

Approximately 850 UK linked individuals of national security concern have travelled to engage with the Syrian conflict. We estimate that just under half have returned and approximately 15% are now dead. This number includes all those of national security concern, not just those affiliated with Daesh.

Data from the Crown Prosecution Service shows that they have successfully prosecuted 10 cases involving 14 defendants who have returned to the UK and are suspected of having fought in Syria and /or Iraq. In compiling this answer, we have learned that the data on this subject which was included in our answer to question HL8065 (11 May 2016) was incorrect, as it included all prosecutions related to Syria and / or Iraq, rather than those related only to people who had returned from Syria or Iraq.

All those who return from engaging in the conflict in Syria and Iraq can expect to be subject to investigation to determine if they have committed criminal offences abroad or represent a threat to our national security. Decisions to prosecute are taken, independently of Government, by the Crown Prosecution Service. Assessments are also made of the appropriateness of other forms of intervention, for example including referral to mental health services or to the Channel programme. For reasons of national security, we do not comment further on action taken with respect to returners from Syria.
