Duchess of Cambridge Kate Middleton wore a mulled-wine colour coat and hat this morning as she joined the royal family for Christmas Day for the first time.
The royals traditionally gather at Sandringham for Christmas. Philip normally walks the few hundred yards from the main house to the church and is not thought to have missed a Christmas Day service before.
Well-wishers called out with questions about the Duke, but members of the family did not respond.
The Duchess of Cambridge is spending her first Christmas as part of the Royal Family following her marriage to Prince William, now the Duke of Cambridge, in April.
By 9.30am hundreds of people were waiting at the gates, with queues stretching back around 300 yards.
Veteran royal-watcher Mary Relph, 77, from Shouldham, near Sandringham, said the royals had been spending Christmas at Sandringham for the last two decades and queues had never been as long.
"I have never seen queues like this on Christmas Day before, I have never seen this amount of people here since Diana was alive," she said.
"People are obviously coming to see Kate Middleton."
