A teenager who was born with a life-threatening birth defect has returned to the hospital where he was treated to share his championship swimming medals.

Ashby had surgery at Bristol Royal Hospital for Children when he was six-and-a-half days old to fix a hole in his diaphragm which went undetected during his mother's pregnancy.

The 15-year-old began swimming competitively when he was nine, before going on to win multiple competitions and a national championship.

Ashby's mother Sarah said: "For us the memory of those early days is a trauma we carry with us, but we've been incredibly fortunate. The NHS, our consultants, and his coaches have given Ashby the chance to thrive."
