It is also believed she may no longer join the Royals on the public stage, which includes Christmas at Sandringham.
Former BBC royal correspondent Jennie Bond told The Mirror: “I think it’s inconceivable that Andrew and Sarah could appear in public at Sandringham.
“And if they joined the family party but kept away from the public and the cameras, it could open up the King to charges of hypocrisy.
“It’s another very tricky domestic situation for Charles . He is a sensitive man, and family is important to him. Nothing can change the fact that Andrew is his brother.”
She continued: “But these latest revelations about Fergie‘s association with Jeffrey Epstein – and the prospect that there is more to come – make it impossible for her to be part of the inner family circle again.”
Bond also said that the scandal could be the “permanent end” to Andrew and Sarah’s Christmas appearances with the royals at Sandringham.
Prince Andrew and Sarah’s daughters Princess Eugenie, 35, and Princess Beatrice, 37, have not commented on the latest scandals their parents have found themselves involved in.
However, royal expert Richard Fitzwilliams told Express.co.uk that the sisters are likely to find their parent’s situation “devastating”.
