Jeremy Corbyn has suggested the UK could keep its Trident submarine fleet but without carrying nuclear warheads. <br />The Labour leader told the Andrew Marr Show there were "options" for maintaining defence jobs while showing the UK was willing to take a lead in nuclear "de-escalation". <br />Mr Corbyn told the BBC that Trident was a relic from a "cold war generation" that was not capable of protecting the UK from current threats.
