The search for British TV doctor Michael Mosley, known for popularising the 5:2 diet and for his appearances on The One Show and This Morning, is in its fourth day after he went missing on the Greek island of Symi on Wednesday afternoon. Here is what we know so far:
Mosley, 67, was last seen leaving Agios Nikolaos beach, where he had been with his wife, Dr Clare Bailey, at about 1.30pm local time on Wednesday. He did not have his mobile phone on him.
Bailey alerted the authorities after he failed to return by 7.30pm and they were unable to locate him overnight. On Saturday the search operation was in its fourth day.
CCTV footage from a restaurant has shown Mosley in the village of Pedi, proving he reached the area about 20 minutes after he departed from the beach.
