The father of British snowboarder Ellie Soutter who died on her 18th birthday believes she could have been struggling with the pressure of competing in high-level sport.
Tony Soutter told BBC South East he had lost his best friend, his “total buddy” and his rock.
Ellie “wanted to be the best” and not “let anybody down”, he said.
UK Sport said it was working with partners to provide appropriate support for athletes.
