10 reasons why we love Prince Philip

At age 93, Prince Philip is the longest-serving and oldest-ever spouse of any reigning monarch — and yet the spritely Duke of Edinburgh shows no signs of slowing down.

Having just returned from a high-profile engagement in France to commemorate the 70th anniversary of D-Day, Philip will celebrate his birthday (June 10) at the annual Buckingham Palace garden party this week, where he will enjoy tea and sunshine with more than 8,000 distinguished guests, including his grandson, Prince William, and William's wife, the Duchess of Cambridge née Kate Middleton.

To celebrate Prince Philip and his longstanding love for the Queen after all these years, Hello! Online rounds up 10 fun facts about His Royal Highness.

2. He's very sporty. At school, the Prince – a born athlete – showed his athletic prowess and soon won the captaincy of both the hockey and cricket teams. Later in life, he was an avid polo player and sailor.

3. He’s an animal lover. He was president of both the Zoological Society of London (1960-1977) and the World Wildlife Fund (1981-1996). His son, Prince Charles, and grandsons, William and Harry, are following in his footsteps with their ongoing dedication to conservation efforts.

7. He never quits. After being told he could no longer play polo because of arthritis, Prince Philip took up the sport of carriage driving. This is how he describes his new passion: "I am getting old, my reactions are getting slower, and my memory is unreliable, but I have never lost the sheer pleasure of driving a team through the British countryside. I have been fortunate to have had longer innings than most, and I have no intention of giving up while I have a team of willing ponies and dedicated staff and while I can still cope with the challenges which carriage driving presents me with."

8. He loves country life. When relaxing at the royal Estates of Sandringham and Balmoral, the Duke indulges in hunting, riding and even barbecuing!

9. He's a snappy dresser. He attends hundreds of events every year and is always impeccably suited up for the occasion, from his top hat and tails at the Queen's Diamond Jubilee celebrations to handsome fedoras while carriage driving and Burberry trench coats on official outings.
