Nick Clegg and his wife Miriam Gonzalez Durantez have revealed their eldest son has spent the past year battling a rare form of blood cancer.
Speaking to ITV this morning the former deputy Prime Minister made a plea for new treatments and kinder cures after his 14-year-old battled with Hodgkins Lymphoma.
Speaking about how the family dealt with the teenager's condition, Miriam said they tried to keep their routine as normal as possible.
'The day that he was told, and I think that probably us telling him is one of the toughest things that we have ever done, the following day he went to school, he stood up and he told everybody "I have cancer"'.
Nick, who was the leader of the Liberal Democrats between 2007 and 2015, also opened up about how the condition impacted him as a dad.
"Certainly if you are unfamiliar with it, as we were, and your initial reaction, I think, we found, was like any mum and dad, it's irrational, but you just have this nearly physical wish to try and take it off your kid and take it yourself".
He found a small, painless lump in his neck and tests revealed he also had lymphoma across his chest when he was diagnosed in September past year.
"Interestingly the thing he was most concerned about was sort of falling behind his classmates". So it was very impressive actually'. They appeared on the show to raise awareness for Bloodwise, a charity carrying out important research into blood cancer.
Clegg told the charity that his first reaction 'was an overwhelming, if irrational, wish to take the cancer away from him and take it on ourselves'.
An ultrasound scan and biopsy revealed stage 2 lymphoma, and Antonio was treated with four monthly cycles of chemotherapy, a course of heavy steroids, and a barrage of medication.
'At one point his treatment meant he was taking over 20 tablets per day.
However, the side effects described by Antonio are said to not be unusual, and the Bloodwise report highlights the need for more research to find better, less toxic treatments for children.
