They have two daughters, Princess Beatrice and Princess Eugenie, born 8 August 1988 and 23 March 1990 respectively. They are currently seventh and eighth in line to the throne.
The Duke and Duchess separated in 1992, amidst long periods of separation caused by his military career and media attention towards the Duchess, and divorced in 1996.
However, the couple committed to raising their daughters together and have maintained a healthy relationship post-divorce. They are often dubbed by the media as the world’s happiest divorced couple and still live and holiday together.
