The Prince of Wales paid a heartfelt tribute to the Queen, his grandma who died aged 96.
The Prince - who has Prince George, nine, Princess Charlotte, seven, and Prince Louis, four, with the Princess of Wales - also admitted he was still trying to come to terms with the loss of his grandmother.
He said in a statement: "On Thursday, the world lost an extraordinary leader, whose commitment to the country, the Realms and the Commonwealth was absolute. So much will be said in the days ahead about the meaning of her historic reign.
"I, however, have lost a grandmother. And while I will grieve her loss, I also feel incredibly grateful. I have had the benefit of The Queen’s wisdom and reassurance into my fifth decade. My wife has had twenty years of her guidance and support. My three children have got to spend holidays with her and create memories that will last their whole lives.
"She was by my side at my happiest moments. And she was by my side during the saddest days of my life. I knew this day would come, but it will be some time before the reality of life without Grannie will truly feel real."
"I thank her for the kindness she showed my family and me. And I think her on behalf of my generation for providing an example of service and dignity in public life that was from a different age, but always relevant to us all"
Prince William will honour Queen Elizabeth's memory by supporting his father, The King.
