A navy officer was unlawfully killed by a junior rating on board a nuclear submarine, a coroner has said.

Able Seaman Ryan Donovan, 23, shot Lt Cdr Ian Molyneux, 36, of Wigan, Greater Manchester, at close range on HMS Astute in Southampton.

He had been on a two-day drinking binge before the attack in April 2011.

Recording a narrative verdict, Coroner Keith Wiseman said he would recommend that random breath testing for Royal Navy personnel be implemented.
