An investigation into claims made by a Royal Navy submariner has found no safety or security breaches on Britain’s nuclear armed submarines.
Able Seaman William McNeilly went absent without leave (AWOL) after posting an 18-page document online in which he criticised Trident's safety and security procedures, saying they were a "disaster waiting to happen". He later handed himself in to police.
In a written statement, the Defence Secretary Michael Fallon told MPs many of the claims were factually incorrect. He said:
“Most of McNeilly’s concerns proved to be either factually incorrect or the result of mis- or partial understanding; some drew on historic, previously known, events none of which had compromised our deterrent capability and, where appropriate, from which lessons had been learned to develop our procedures as part of a continuous improvement programme."
“He was under training, and his access and exposure to activities and material on board were appropriate to his security clearance.
"We have found no evidence that he raised any concerns with colleagues on board or with the chain of command: had he done so, the more senior and experienced submariners would have been able to explain how the boat operated and why McNeilly’s concerns were unfounded.
"A number of the issues he raised did not occur during his patrol."
