The heir to the throne - whose daughter-in-law Duchess Catherine is a week overdue with her second child - made the admission when joking with Eric Jones, the oldest surviving member of the Welsh Guard, about the difficulties of raising girls.

The retired soldier's daughter, Lynda Bateman, who attended a reception with Eric at Windsor Castle yesterday (30.04.15), said: "My father introduced me as his daughter and Prince Charles asked how many daughters he had.

"My father said 'One - and that's enough', and Charles laughed and said 'And we're hoping for a granddaughter!' "

The 66-year-old prince is already grandfather to Catherine and his son Prince William's first child, 21-month-old Prince George, and his wife Duchess Camilla has five grandchildren from her first marriage.

Charles has previously admitted he hopes the new addition to the family will be a princess.

Speaking shortly after it was announced Catherine was pregnant again, he said last year: "I'm happy I'm going to be a grandfather again. I'm looking forward to it - but I hope it will be a girl this time."

Another attendee at the event, Maureen Morris, asked Camilla if there had been any news as to whether Catherine - who was known as Kate Middleton - had gone into labour yet.

Maureen said: "She said 'No'. I said 'It will be great when it happens.'
