King Charles III has released a statement following his mother's death.
The King's statement says: "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.
"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."
Charles and his siblings had all travelled to be with her at Balmoral in Scotland, before her death was announced early on Thursday evening.
