Sarah Ferguson smuggles boxes of diaries out of the Royal Lodge

The insider continued: “Sarah has reached a stage where she feels like she has little left to protect. She is determined not to sink alongside Andrew, and there is a growing belief that she could reveal deeply damaging information if necessary to protect herself.”

The tipster said the tension is being felt strongly by the couple’s daughters, Princess Beatrice, 37, and Princess Eugenie, 35, who are reportedly “mortified” by the constant headlines about their parents.

Windsor’s association with Epstein determined his downfall.

He was accused by the pedophile’s most high-profile victim, Virginia Giuffre, of sexually abusing her as a teenager after she was trafficked by Epstein and his colleague Ghislaine Maxwell, who is now serving a 20-year prison sentence.

Windsor has consistently denied the allegations. New claims about him emerged in Giuffre’s posthumously published memoir, completed shortly before her death by suicide at age 41 earlier this year.

She claimed she met the then-prince when she was 17, and says he bedded her three times. Giuffre said Maxwell told her to “do for (Windsor) what you do for Jeffrey,” and that after the meeting, Epstein paid her $15,000 and Maxwell told her, “The prince had fun.”

Giuffre also claimed to have had two more encounters with Windsor, including what she described as an “o—” involving several other underage-looking girls.

He settled Giuffre’s civil case against him in 2022 for about $15 million out of court without admitting liability, and in October he was stripped of his royal titles by King Charles.
