A Royal Navy nuclear submarine arrived in a port city yesterday almost a year after an officer was killed on board a sister vessel during an almost identical visit.

HMS Tireless is visiting Southampton, Hampshire, for five days, giving local dignitaries, sea cadets, Scouts and other youngsters an opportunity to sample life on board.

In April last year, during a visit by HMS Astute to Southampton, Able seaman Ryan Donovan killed Lieutenant Commander Ian Molyneux and shot Lieutenant Commander Christopher Hodge in the stomach.

Donovan was later jailed for life and told he would serve at least 25 years in prison.

The murder happened during a visit by civic dignitaries.

HMS Tireless will leave Southampton on Tuesday.
