The Prime Minister is under pressure to reveal what she knew about a reported misfire of a Trident missile by a Royal Navy Submarine in June last year.

It happened just weeks before the Commons voted to spend 拢40bn renewing the nuclear deterrent.

The Ministry of Defence says that the test fire of the unarmed missile off the coast of Florida was successful, but it's now emerged that there was a problem with the missile during its flight.

5 live spoke to former Submarine Commander, Steve Aiken, who said Theresa May is 鈥渆xactly right鈥� not to comment.

He said: 鈥淭here is a convention that we don鈥檛 talk about issues to do with a deterrent, we don鈥檛 talk about submarine operations.鈥�

鈥淥f course it has to be secretive, it鈥檚 the nuclear deterrent and the main insurance policy that this country has,鈥� he added.
