His wife, Dr Clare Bailey, alerted authorities after he failed to return by 7.30pm, but they were unable to locate him overnight. A post has been shared in a local Facebook group appealing to anyone on the island of about 2,500 people who might have seen Mosley.

It said: “A search and rescue team is coming from Athens with drones and other more sophisticated equipment to extend the search. Have you seen this man? He set off to walk back from St Nick’s at about 13.30 and failed to make it home. His friends are concerned as it is 6 hours since they last saw him. His name is Dr Mike Mosley and he is a familiar face for many British people.”

Mosley is a columnist for the Daily Mail, and MailOnline news website alongside the newspaper, and has made a number of documentaries about diet and exercise, including the Channel 4 show Michael Mosley: Who Made Britain Fat? He was also part of the BBC series Trust Me, I’m A Doctor.
