The Prince of Monaco has become the first European monarch to send his good wishes to the British monarch since Buckingham Palace announced his cancer diagnosis.
In a statement, Albert said: "Your Majesty, In these difficult times, my family would like to express to you our full support.
"Your determination, courage and openness have always been a source of inspiration.

Although Albert was the first European monarch to wish Charles well, he was not the first European member of a Royal Family to do so.
