Question to the Home Office:

To ask the Secretary of State for the Home Department, how many UK citizens returning to the UK after joining Daesh in (a) Syria and (b) Iraq have been (i) interviewed under caution and (ii) charged with criminal offences.

The Home Office Statistical Bulletin on the Operation of police powers under the Terrorism Act 2000 and subsequent legislation publishes data about convictions quarterly but does not distinguish those which relate to Syria, Iraq and Daesh. British Citizens who are investigated and charged with offences relating to the conflict in Syria and Iraq will be prosecuted in accordance with the Code for Crown Prosecutors.

Although official figures do not show how many were Syria, Iraq or Daesh related, of the 105 persons charged with a terrorism-related offence in the year ending June 2017, 33 had been prosecuted (as at the time of data provision to the Home Office, 14 July 2017), 32 of which were found guilty. A further 68 were awaiting prosecution.
