Nick Clegg describes coping with son's blood cancer

The former British Deputy Prime Minister Nick Clegg and his wife have described the moment they had to tell their eldest son he had blood cancer as one of the "toughest things" for their family.
Mr Clegg and his wife Miriam Gonzalez Durantez told ITV's Lorraine Kelly how their son Antonio, now 15, was diagnosed with Hodgkin Lymphoma in September last year.
