Question to the Home Office:
To ask the Secretary of State for the Home Department, what her most recent estimate is of the number of British nationals suspected to have left the UK to join Islamic extremist groups in other countries.
We have stated publicly that around 600 people from the UK who are of interest to the security services are thought to have travelled from the UK to the region of Syria and Iraq since the start of the conflict. Given our longstanding policy not to comment on intelligence matters, we are unable to comment further on travel by British nationals to join extremist groups abroad.
