A search was launched and he was found some 90 minutes later, about a mile north-east of Cava Lighthouse, Orkney.

The diver, reported to be 64 years old, was recovered from the sea by the Longhope RNLI lifeboat, but confirmed dead by a paramedic brought by a Coastguard SAR helicopter from Sumburgh.

“The diver was treated with respect and dignity by the volunteer crew-members and taken to Stromness," the RNLI stated.

"RNLI Longhope would like to offer their condolences and deepest sympathy to his family, friends and loved ones.”
