Former Duchess of York Sarah Ferguson is ‘loyal’ to King Charles and the royal family, a royal expert has claimed.

Royal expert Richard Palmer has made these claims in his report for the i Paper amid speculations Sarah is considering six-figure offers to write a tell-all book.

Palmer dismissed claims with a source saying, “She would never do anything like that. When has she ever written a tell-all book or threatened to do anything like that? That’s not Sarah.”

Earlier, royal expert Mark Dolan told the SkyNews, Sarah ‘needs the cash’, and it’s very possible that she will sign a million-dollar deal to spill the beans.

“The big problem is for Charles because this whole scandal threatens to taint his entire reign as monarch,”, the expert said.

However, Richard Palmer said indeed, were Sarah to write a book, it would make life even more difficult for her two daughters, Princess Beatrice and Eugenie.

Eugenie and Beatrice have already been left in an unenviable position following their parents’ very public fall from grace, and King Charles has gone out of his way to ensure they are still valued members of the royal family, despite neither undertaking official duties.

There were also claims Sarah was considering ‘six-figure offers’ for a tell-all interview in the wake of losing her Duchess of York title.

The insiders recently told the Sun, “There’s a danger of her going rogue and saying things that could cause embarrassment for King Charles and Queen Camilla, or other members of the family.”
