Experts say that Prince William and Kate Middleton are the most glamorous royal couple.
On the occasion of his 40th birthday, expert Richard Fitzwilliams has called the Duke of Cambridge and his wife Kate Middleton "perfection".
He told the Daily Star: "Prince William's inspiration is, as he has said, the Queen. His partnership with Catherine and the way they work together, on charitable issues and on foreign tours, is perfection.
"Katherine has not only been amazingly supportive, but has also grown in confidence, especially as a speaker. They are also the most glamorous royal couple in the world.
“It helps spread the word and is also useful for soft power, as the government uses their foreign trips to promote goodwill,” he concluded.
