A Trident whistleblower has claimed a fake ID is ‘all it takes’ to gain access to Britain’s nuclear weapons.
William McNeilly, a former Royal Navy submarine engineer, also alleged thousands of Royal Navy IDs go missing every year and could be used to access a nuclear submarine.
His comments come as thousands of people joined Labour leader Jeremy Corbyn in a protest against Trident in London today.
Mr McNeilly also claimed terror groups such as ISIS would be capable of producing a fake document good enough to breach security.
In an interview with RT (formerly Russia Today) he said: “All you need to get on board is a couple of fake IDs. Terrorist groups like Isis have already shown they can produce legitimate documents.”
“Thousands of Royal Navy IDs go missing every year as well, so they could come across one,” he continued.
“All it would take would be for one of them to have a bomb.”
Claims: William McNeilly alleges Trident security is inadequate
Risk: Mr McNeilly said ID cards such as this can be easily forged or obtained
He spoke after posting a 15-page document online claiming he was present during a number of inadequate security checks while training with the Trident programme.
However the Ministry of Defence have labelled his claims ‘complete nonsense’ and described its security measures as ‘rigorous’.
A spokesman said: “Rigorous security measures are in place at HM Naval Base Clyde and it is nonsense to suggest otherwise.
“We simply do not accept that a fake ID would gain you access to a nuclear submarine.”
The overall cost of replacing Britain’s Trident nuclear systems would be £167bn – double previous estimates – according to recent calculations based on official figures.
Concerns: The whistleblower also claimed terrorists could gain access to nuclear submarines
Base: Trident is operated from the Clyde Naval Base in Scotland
Thousands have flocked to central London to protest against the renewal of the multibillion-pound nuclear system today.
Led by the Campaign for Nuclear Disarmament, anti-nuclear protesters from across the UK armed themselves with placards and banners as they braced the bitter winds to spread their message.
The group – estimated by stewards to run into “many tens of thousands” – were joined on the marches by Labour leader Jeremy Corbyn and SNP leader Nicola Sturgeon.
Arriving fresh from a Labour hustings in the north of England, Mr Corbyn said: “If a nuclear war took place there would be mass destruction on both sides of the conflict.
“Everyone should think about the humanitarian effects on people across this globe if they’re ever used.”
