Labour's credibility on defence is in tatters after Jeremy Corbyn ruled out ever using Britain’s nuclear deterrent, refused to back a drone strike to kill Isil’s leader and said he would suspend air strikes on Syria.

Mr Corbyn’s comments were widely condemned by senior military figures and Labour MPs amid warnings that the nation will not be safe in his hands.

Within hours of his interview, the Labour Party was forced to issue an embarrassing statement clarifying that it still supports the Trident nuclear deterrent.
