The SNP leader admitted the word "national" could be "hugely problematic".
Trident Safety Fears Rejected
Concerns about Trident raised by Royal Navy submariner William McNeilly were either incorrect, the result of misunderstanding or based on historic events, and safety has not been compromised, Defence Secretary Michael Fallon has said.
Mr Fallon said a Ministry of Defence (MoD) investigation into claims made by Able Seaman McNeilly has found that neither the operational effectiveness of Trident nor the safety of the public or submariners have been compromised.
The 25-year-old sailor went absent without leave earlier this month after producing an 18-page report containing a series of allegations about the Trident submarines based at Faslane on the Clyde in Scotland.
Mr Fallon said McNeilly is being confined to a "specified location'' in Portsmouth where he is being interviewed and is being "afforded the duty of care that we give all our personnel''.
In a written ministerial statement, Mr Fallon said: "Having now completed our investigation, and having consulted with the appropriate regulatory and operating authorities, I can assure the House that neither the operational effectiveness of our Continuous at Sea Deterrent nor the safety of our submariners or members of the public have been compromised.''
The Defence Secretary said that only one of Able Seaman's McNeilly's claims, that e-cigarettes are being used inside submarines, needs to be investigated further but there is "clear evidence'' that their use does not but the safety of the boats at risk.
Mr Fallon 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.
"Only one of the allegations remains to be fully examined - the allegation that e-cigarettes were being used within the submarine.
"No independent corroboration of this has been found but even if it were true, there is clear evidence that their use did not put the safety of the boat at risk.
"Able Seaman McNeilly was arrested having not reported for duty after a period of leave.
"He was released the next day, but confined to a specified location in Portsmouth while interviews were conducted.
"He is being afforded the duty of care that we give all our personnel, is in contact with his family, and is still in the employ of the Royal Navy.''
A police watchdog probe was launched after the remains of the 52-year-old were found in a house in Dumfries in February last year.
The accident happened at about 7.50pm on Thursday in Moodiesburn, North Lanarkshire.
More than 70 firefighters were needed to bring the blaze under control at Blochairn Fruit Market in the early hours of Thursday.
