Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Statement of 28 May 2015 on safety at HM Naval Base Clyde, what the terms of reference are for the investigation into the alleged use of e-cigarettes on an active Vanguard submarine; and when this investigation will conclude.

The use of electronic cigarettes is being examined by the Institute of Naval Medicine to ascertain if certain products may be suitable for use onboard submarines in the future. Their use is prohibited in submarines, and the Command is reminding all personnel of the Ministry of Defence policy that electronic cigarettes may be used only in designated smoking areas.
