Prince William reportedly dislikes Sarah Ferguson and how she treated his late mother, Princess Diana.

On the Royals podcast, an insider claimed that it became Ferguson’s mission to humiliate the Princess of Wales.

“She would say snide things in public, and even put in her biography that Diana gave her foot warts! Di was mortified and Fergie found herself very much cut from the social scene until Diana passed,” the insider said.

The insider also said that even though royal fans may have already forgotten what Ferguson did to Princess Diana, this is something that the Duke of Cambridge remembers to this day.

“He never liked Fergie and her passive-aggressive ways. He’s heard all about how fractured things got between her and his mum, of course, and he’s determined that Diana shall get the last word in, even from beyond the grave,” the source said.

When the time comes, Prince William will be given an unprecedented amount of power by Queen Elizabeth. And the source said that one of the queen’s instructions for her grandson is to examine Prince Andrew’s role to the monarchy.

The Duke of York stepped down from his royal duties last year amid claims of sexual abuse and harassment. But there are reports that she and Ferguson still receive financial support from the queen and the royal family.

But when Prince William ascends the throne, it is reportedly not unlikely for him to banish his uncle for good.

“William believes they have no right to be coddled and cozy within one of the family’s most regarded residences and has made noises about moving them to a less envious postcode to reflect their status,” the source said.

But the Duchess of York reportedly thinks this is Prince William’s way of getting his revenge for Princess Diana. Prince William and the Princess of Wales reportedly have a ton of similarities.

“Of course, William wouldn’t admit outwardly that his motivations are petty, but getting one back on Fergie has to make him feel closer to the mum he lost at such a young age,” the source said.

Prince William has not publicly bashed Prince Andrew and Ferguson in any way. And it’s unlikely for the future king to be plotting against the former royal couple.
