Prince William "eats a lot" at Christmas.
The 39-year-old royal - who has children Princes George and Louis, 8 and 3, and Princess Charlotte, 6, with wife Catherine, Duchess of Cambridge - admitted food is "quite important" to him over the festive period and no matter how full he feels, he can always find space for an extra sausage or glass of wine.
Answering questions from young patients at the Royal Marsden London on the facility's radio station, he said: "Food is quite important to me on Christmas, I tend to eat a lot on Christmas. There's always a tiny bit of space left in my stomach somewhere for a bit more bit of turkey or sausage or for the wine."
William added that he loves Brussels sprouts and told the youngsters it was important to eat vegetables.
