Britain’s Trident deterrent system is neither unsafe nor insecure, the government has said.

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 said.

Mr Fallon said a Ministry of Defence investigation into the claims found that neither the operational effectiveness of Trident nor the safety of the public or submariners have been compromised.
