An unarmed British Trident missile went wildly off-course during a test in June 2016, and was destroyed off the coast of Florida, US sources told CNN on 23 January, following a report in the Sunday Times.
This information was not given to the house of commons before it voted to replace the Trident nuclear weapons system in July.
Caroline Lucas, co-leader of the Green Party, said: ‘A missile veering off course is deeply concerning. Imagine such a failure occurring in a “real-world” situation - it could lead to the slaughter of millions of people in an ally’s country.’
