Question to the Ministry of Defence:
To ask the Secretary of State for Defence, how many fires have taken place on UK (a) nuclear-powered and (b) nuclear-armed submarines in the last five years; and how many of those fires on submarines occurred (a) at sea and (b) while berthed.
The historical nature and scope of the information requested is such that it will take time to collate. Once this process is completed I will write to the hon. Member.
