Her Majesty is currently residing at Windsor Castle, where she spent Christmas with her eldest son, the Prince of Wales, and the Duchess of Cornwall.
In her Christmas Day broadcast, the Queen paid tribute to her late husband, the Duke of Edinburgh, who passed away at the age of 99 in April 2021.
"Although it's a time of great happiness and good cheer for many, Christmas can be hard for those who have lost loved ones. This year, especially, I understand why," she said. "But for me, in the months since the death of my beloved Philip, I have drawn great comfort from the warmth and affection of the many tributes to his life and work – from around the country, the Commonwealth and the world."
