A search and rescue operation is under way, including a police dog and a drone searching hard to reach areas.
The 67-year-old former medical doctor is known for appearing on television programmes like This Morning and The One Show, and presenting Trust Me I’m a Doctor on BBC Two.
Senior Greek police spokesperson Constantina Dimoglidou confirmed searches for the star began early on Thursday morning, with no trace yet found.
He went missing after he set off hiking along St Nicholas Beach on Wednesday lunchtime. “He was at the beach of Ag. Nikolas with another couple when he decided to go back to his home in the area of Pedi of Symi,” the spokesperson said.
