A body has been found in the search for TV and radio presenter Michael Mosley, a rescue worker tells the BBC.
The 67-year-old went missing on Wednesday after setting off on a walk from Agios Nikolaos beach.
The body - which has yet to be formally identified - was found on a cliff on a rocky hill north-east of the village of Pedi, near Agia Marina beach.
Authorities had been searching for Dr Mosley in a remote mountainous area.
Symi's mayor said the body was found as teams were searching the coastline with cameras and were approaching a cave next to Agia Marina beach.
A police source told BBC News the deceased had been dead "for a number of days".
Greek authorities have been searching for Dr Mosley over five days, and the effort has included firefighters, dogs, helicopters, drones, local people and officers from Symi and outside the island.
His four children had also joined his wife, Dr Clare Bailey Mosley, on the island.
Dr Mosley is best known for his TV programmes including Trust Me I'm a Doctor and BBC Radio 4's Just One Thing podcast.
Dr Mosley studied medicine in London and qualified as a doctor and for the last couple of decades has been working as a presenter, documentary maker, journalist and author.

Dr Mosley is also columnist for the Daily Mail and his TV programmes also include Channel 4 show Michael Mosley: Who Made Britain Fat? and BBC show Trust Me, I'm A Doctor.
