A British man has been reported missing on a solo round-the-world sailing trip after his faithful dog was discovered alive on board his abandoned yacht drifting off the Canary Islands.

James Nunan, 34, from Reading, set off on his dream voyage in March with his miniature Jack Russell, Thumbelina, aboard a boat called Kehaar that he had bought in Slovenia.

But fears are growing for the adventurer after his yacht was found by coastguards 50 miles off Gran Canaria with no sign of its owner - though documents inside confirmed it belonged to him.

Miraculously, little Thumbelina was discovered unharmed and has since been taken in by a local dog shelter.

Nunan, a builder affectionately known to family as 'Jemsie', had last been in touch with his mother, Maura Norton, 56, from Essex, on August 18.
