Britain's first 'guide horse', who was sacked for being too big, has found a new home with a partially sighted Office for National Statistics worker in London.

Digby, who is an American Miniature horse, became Britain’s first ‘guide horse’ when he began training with BBC journalist Mohammed Salim Patel in February.

But due to an unexpected growth spurt, which took Digby to the height of 33 inches, Mr Patel decided the horse was too large to guide him around his office in Salford, Greater Manchester.

He said the animal had become inconvenient because it would knock items off the shelf in supermarkets and couldn't fit under his desk at work like a guide dog could.

However, Digby's special training will no longer go to waste as partially sighted Helena Hird, who works for the ONS in London, has decided he's not too big for her.
