The duchess - who is married to Britain's Prince Charles - is said to be furious with how she is treated by some of the junior members of the royal family during the annual festivities at Queen Elizabeth's royal Norfolk estate, Sandringham, and would prefer to give it a miss.
Camilla, the Duchess of Cornwall, wanted to boycott the British Royal Family's Christmas celebration because she is "not being shown enough respect".
The duchess - who is married to Britain's Prince Charles - is said to be furious with how she is treated by some of the junior members of the royal family during the annual festivities at Queen Elizabeth's royal Norfolk estate, Sandringham, and would prefer to give it a miss.
A source said: "Camilla feels some of the junior royals and members of the queen's household look down their noses at her. If that's the way they feel about her she would rather be with her own family anyway."
Camilla - who became a grandmother when her son Tom Parker Bowles and his wife Sara had their first child Lola in October - is also upset she cannot see her baby granddaughter on the special day and is getting increasingly frustrated with all the sacrifices she is expected to make now she is a royal.
The source added to Britain's Daily Express newspaper: "Charles has always been a selfish, self-centred quirky individual and he is continuing with his life in much the way he did as a young man.
"Camilla is the one who makes all the sacrifices. She never wakes up with her real family on Christmas day any more. Even friends have fallen away because it's just so difficult to stay close to a member of the royal family."
