The Foreign Office has confirmed that a British man has died, and several other tourists are in hospital after a boat capsized while on a seal-watching trip at Hout Bay near the western city of Cape town, in South Africa, on Saturday afternoon.
The man has been named in media reports as 64-year old Peter Hyett from Barry in the Vale of Glamorgan.
Mr Hyett was holidaying in South Africa with his wife Suzanne, 63, and her daughter Helen, 37, both of whom survived the accident and were treated in hospital.
They were due to return to the UK at the weekend.
The body of South African tour guide John Roberts was also found after the rescue effort.
At least 24 survivors were taken to hospital with serious or minor injuries and many of them were foreign nationals.
Most of the casualties have now been released.
It remains unclear what caused the boat to capsize near Duiker Island which is popular with tourists hoping to catch a glimpse of the thousands of seals found there.
Brad Geyser, the joint operations commander for South Africa's National Sea Rescue Institute, tells ITV Wales of the dramatic rescue.
