A man who went missing five weeks ago in south-western France has been found alive in an underground cave system where he had got lost. Jean-Luc Josuat-Verges, 48, told police he survived by eating wood and clay.

He was found thanks to some teenagers who had been exploring the caves, which are normally closed to the public.

Mr Josuat-Verges left his home on 18 December suffering from depression and telling his wife he wanted to be alone for a time, local newspapers said.

Taking a bottle of whisky he drove his jeep to an abandoned mushroom farm consisting of a vast network of underground tunnels.

But in the pitch blackness he got lost and for the next 35 days he had to survive as he could.

Wrapped in plastic sheeting, he said he ate wood and clay, which may have been the remains of the mushrooms.
