Question to the Home Office:

To ask Her Majesty's Government how many individuals who went from Britain to Syria to join ISIS are known to have returned to date; and how many of these were (1) detained on arrival at the UK border, (2) allowed to return to the UK without any restriction on their movements, (3) are currently detained awaiting trial, (4) are on bail, and (5) are serving custodial sentences.

As confirmed in UIN 116493, approximately 400 UK-linked individuals of security concern have returned from the conflict in Syria. Due to operational sensitivity, we cannot provide a breakdown of how each case is being managed.

The Home Office Statistical Bulletin publishes data about convictions quarterly but does not distinguish those which relate to Syria 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 or Daesh related, of the 97 persons charged with a terrorism-related offence in the year ending September 2017, 30 had been prosecuted (as at the time of data provision to the Home Office, 6 November 2017), 30 of which were found guilty. A further 65 were awaiting prosecution.
