Philippe, Crown Prince of Belgium

Crown Prince Philippe of Belgium is the eldest son and heir apparent of Albert II, King of the Belgians. He is married to Mathilde d'Udekem d'Acoz and together they have one daughter, Elisabeth[?], who, when inaugurated, will become the first Queen of the Belgians. Princess Mathilde will become the first Belgian Queen to have Belgian nationality, when her husband assumes the throne.

For some years, Philippe, though second-in-line to the throne, was treated as being the Heir Presumptive of his childless uncle, King Baudouin. However on Baudouin's death, the first-in-line, the late King's brother, Albert, chose to become king himself. It is believed that Philippe's then unmarried status was the reason why his father opted unexpectedly to take the crown.
