Nick Clegg, the former deputy prime minister, and his wife Miriam have revealed their teenage son's battle with blood cancer.

The couple today disclosed that 14-year-old Antonio was diagnosed with Hodgkin lymphoma - a rare form of the disease - in September last year.

After several months of chemotherapy, their eldest son - now 15 - has now been given the all-clear.

Mr Clegg, the former Liberal Democrat leader, and his wife, Miriam Gonzalez Durantez, told how having to tell Antonio that he had blood cancer was one of the "toughest things".
