Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many service personnel in the (a) Army, (b) Royal Navy and (c) the RAF have been (i) investigated by and (ii) discharged from the services as a result of (A) membership of national action (B) membership of a far right organisation, (C) anti-Semitic organisations and (D) Islamophobic organisations; and if she will make a statement.

Since April 2007 (when offences started to be recorded on the Joint Personnel Administration system), no members of the Royal Navy or Royal Air Force have been investigated or discharged from Service as a result of membership of the named organisations.

During that time, less than five (this figure is rounded to avoid identification) members of the Army were investigated and discharged due to membership of National Action.

Extremist ideologies are completely at odds with the values and standards of the military. We have robust measures in place, including during the recruitment process, to ensure those exhibiting extremist views are neither tolerated nor permitted to serve.

We are working with the Home Office to implement the Prevent programme across the Armed Forces, including training personnel to ensure they are aware of what to do if they believe an individual is showing signs of radicalisation.
