The wife of missing TV doctor Michael Mosley has pledged she won’t “lose hope” after “the longest and most unbearable days” for her family.

Dr Claire Bailey Mosley expressed her gratitude to the dozens of Greek volunteers and emergency workers searching for her husband in the unrelenting heat and harsh terrain of Symi island.

Speaking for the first time since her husband’s disappearance she said in a statement: “It has been three days since Michael left the beach to go for a walk. The longest and most unbearable days for myself and my children.

“The search is ongoing and our family are so incredibly grateful to the people of Symi, the Greek authorities and the British Consulate who are working tirelessly to help find Michael. We will not lose hope.”

Her words came as British volunteers joined the search for Dr Mosley on Saturday as fears intensified for his safety.

A small group of Britons arrived on the island of Symi to join efforts to find Dr Mosley as new CCTV footage of him walking through the port village of Pedi emerged.
