I am surprised William, Kate and their children were not present. I had thought this was a key Royal Family event. I wonder if they will join the family for Christmas Eve?
"The king and Queen Consort Camilla, who are still living in their London residence Clarence House, were the first to arrive. Charles’ brother Prince Edward arrived with his wife, Sophie Countess of Wessex, and their daughter Lady Louise Windsor, who recently finished her first semester at William and Kate’s alma mater St. Andrews in Scotland. Princess Anne and her husband Sir Timothy Laurence also attended, along with Zara and Mike Tindall, and their children, Mia, Lena and Lucas, who were photographed smiling in the backseat of their Range Rover as they left the castle. The Telegraph reported that Prince Andrew was also set to attend, but he was not photographed arriving.
A handful of the late queen’s cousins also made the trip to Windsor. The Duke of Kent, arrived with his granddaughter, Lady Marina Windsor, his daughter, Lady Helen Taylor, and her family. Prince and Princess Michael of Kent also attended.
Usually Prince William and Kate Middleton attend along with their three children, Prince George, Princess Charlotte, and Prince Louis, but this year they were absent, having reportedly traveled to Anmer Hall, their home on the Sandringham Estate, when the term ended at Lambrook, the school they attend in Berkshire."
