After King Charles, William is next in line for the throne, followed by his 9-year-old son Prince George.
William and the former Kate Middleton have yet to share their own personal statement, however, they did retweet King Charles' statement.
"The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family, his statement began. We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world."
"During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which The Queen was so widely held," he continued.
