A coroner has recorded an open conclusion into the death of TV doctor Michael Mosley, who died after going for a walk on a Greek island.
The 67-year-old's body was found four days after a search was launched by emergency services on Symi.
Crispin Butler, the senior coroner for Buckinghamshire, said the broadcaster's death was "indeterminate" and "unascertainable".
He added it was "most likely attributable either to heatstroke [accidental] or non-identified pathological cause".
Mr Butler said: "Michael Mosley collapsed and died on the 5th of June 2024 in a rocky area near Agia Marina Beach, Symi, Dodecanese, Greece.
"There had been high temperatures during this time. Michael's death was not found to be due to homicide, suicide or an accident related to injuries.
"Michael's death was most likely attributable either to heatstroke [accidental] or a non-identified pathological cause. There was nothing of note in toxicology.
"No medical cause of death could be ascertained, meaning Michael's death may have been due to a medical event or as a result of a non-traumatic accident."
Dr Mosley was best known for popularising the 5:2 diet, a form of intermittent fasting, as well as his documentaries on the BBC and the Just One Thing health podcast.
