The test firing of a Trident missile from a Royal Navy submarine has failed, for the second time in a row.
The latest test of the UK’s nuclear deterrent was from HMS Vanguard and was witnessed by the defence secretary.
The missile’s booster rockets failed and it landed in the sea close to the launch site, according to the Sun, which first reported the malfunction.
When on patrol, missiles would usually carry nuclear warheads but they are not fitted for test fires.
The Ministry of Defence said the "nuclear deterrent remains safe, secure and effective".
This is highly embarrassing for both the UK and the US manufacturer of the Trident missile.
