Search for Michael Mosley continues for fifth day

The search operation for missing TV and radio presenter Michael Mosley is continuing for a fifth day on the Greek island of Symi.

The 67-year-old vanished after setting off on a walk on Wednesday.

Searches for the presenter have focused on a rocky area north of the village of Pedi where he was last spotted.

On Saturday, his wife Dr Clare Bailey Mosley said "we will not lose hope".

"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," Dr Bailey Mosley said in Saturday's statement.

"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."

Dr Bailey Mosley has been searching the island assisted by friends. The couple's four children have also arrived on Symi to help.

Michael Mosley went missing on Wednesday after leaving his wife on Agios Nikolaos beach to set off on a walk about 13:30 local time (11:30 BST).

His wife later reported Dr Mosley - who did not have his phone - missing.

BBC News obtained new CCTV footage showing one of the last-known sightings of man believed to be Dr Mosley walking with an umbrella next to the marina in the village of Pedi at about 14:00 local time (12:00 BST) on Wednesday.

The video showed him walking along a path towards rocky hills.

This is where Greek police, firefighters tourists and local volunteers are searching for Dr Mosley.

On Sunday morning, a rescue official in Symi told BBC News he and a sniffer dog were being sent back to Athens.

His dog, Scar, had become exhausted with rocks burning his paw in the hot conditions, an indication of the weather Dr Mosley would have experienced.
