It is understood that Camilla has asked her grandchildren to hold the canopy over her as she is anointed with holy oil during the most sacred part of the ceremony. Duchesses have previously performed the role
A royal source said: “The Queen Consort has said she does not want duchesses. She would like it to be her grandchildren.”
In another break with tradition, a significant role for George, nine, is being discussed. The King and Queen are due to meet the Prince and Princess of Wales soon to talk about possible options.
