The Prince of Wales has said he is "thrilled" by the prospect of becoming a grandfather, after the Duke and Duchess of Cambridge announced this week they were expecting their first child.
Prince Charles also joked: "How do you know I'm not on a radio station?", after presenters of an Australian radio show prank called their way into a conversation with Kate's hospital nurse this week.
The Duchess of Cambridge left hospital today, after three days of treatment for a severe form of morning sickness.
A nurse disclosed information about Kate's condition to two DJs who rang the hospital claiming to be the Queen and Prince Charles.
The Duchess of Cambridge is to spend another night in hospital being treated for acute morning sickness but is said to be feeling better.
