The King has thanked the nation for the outpouring of support and warmth his family has received.
Charles' praise came as it emerged Prince George and Princess Charlotte will join their parents, the Prince and Princess of Wales, at the Queen's state funeral, mourning their great-grandmother with more than 2,000 others at Westminster Abbey.
A minute's silence was held at 8pm on Sunday, with Prime Minister Liz Truss standing outside Downing Street, as the nation paused to reflect on the eve of Queen's burial. In his message issued by Buckingham Palace, Charles said: "Over the last 10 days, my wife and I have been so deeply touched by the many messages of condolence and support we have received from this country and across the world.
