Remembering Horatio - the teenager, killed by polar bear

It was supposed to be an adventure holiday - an expedition to the Arctic Circle. But, it ended in tragedy when Horatio Chapple was killed by a polar bear.

But from his death, a powerful legacy has emerged, as his family launched a charity to create beautiful healing gardens at spinal injury units. The first, at Salisbury District Hospital, has been a great success - and today, plans were unveiled for another.

Horatio's mother, Olivia, has been speaking exclusively to Rachel Hepworth about her extraordinary son.
