The Royal Navy, the Coastguard and RNLI joined forces in Cornwall to rescue a diver who’d been separated from his partner diving a wreck miles off the Lizard Peninsula.

The dive boat sent a mayday call at 2.30pm on Tuesday 1 September, which set off a big combined rescue operation.

The Coastguard called upon the assistance of RNLI lifeboats, a Sea King from 771 (Search and Rescue) Naval Air Squadron and Royal Navy frigate HMS Somerset which was nearby.
