British TV doctor Michael Mosley missing in Greece

Search intensifies for missing TV doctor

Mosley, 67, was last seen on Wednesday when he left his wife to go for a walk.

A search is underway for British TV doctor Michael Mosley, who has gone missing in Greece.

The 67-year-old, who is best known for popularizing intermittent fasting, was last seen on Wednesday when he left his wife to go for a walk on the Greek island of Symi.

Mosley, who has presented several documentaries on health and fitness, is a regular contributor to the BBC.

His wife, Clare Bailey, said she became worried when he did not return home after a few hours.

"He is a very experienced walker and knows the area well," she said.

"But it is unusual for him to be out for so long without contacting me."

The search for Mosley has been hampered by bad weather, but a team of volunteers is continuing to scour the island.

The British Embassy in Athens is assisting with the search.
