Albert II, the father of Belgium’s current King Philippe, was the third and youngest offspring of King Leopold III.
He became monarch on Aug 9, 1993, at the age of 59, taking over after his brother Baudouin died without children.
Albert II reigned until his abdication on July 21, 2013, handing the crown to Philippe, who today is aged 63.
The former king and his wife, Queen Paola, 85, have spaced out their public appearances in recent years.
