Prince Harry allegedly told a friend that the Royal Family would find his bombshell interview with Oprah Winfrey "quite shocking" and insisted that "those Brits need to learn a lesson".
His remarks surfaced days before the release of the much-anticipated Netflix documentary 'Harry & Meghan', which promises to lift the lid on much of the family feuding that has dominated the headlines over the past few years.
Senior royal sources reportedly said Harry's comments ahead of the Oprah interview illustrate his continued grievances with the family.
Just prior to the March 2021 chat, sources said Harry told the friend: "This is going to be quite shocking. Those Brits need to learn a lesson.”
The interview itself saw Harry and Meghan level allegations of racism against the Royal Family and claim that members of the family had ignored Meghan's cries for help when she was suicidal.
Fresh allegations of racism are expected in the new Netflix docuseries.
A source told the Sun : “Some of the comments made by Harry and Meghan are fiery.
“If aired, they will be absolutely explosive. The topic of racism is discussed — plus claims that some royals opposed the marriage. The whole TV project is very driven by Meghan."
Sources connected to the palace have said that any accusations made in the Netflix show will be met with "swift and robust" responses.
They claim that the release of a new trailer for the documentary was deliberately timed to coincide with William and Kate's US trip, which concluded on Thursday.
Other topics expected to be covered in the Netflix show include Harry's therapy following the death of Diana and his father's affair with Camilla.
A senior source said that, in private, King Charles and his family have made "numerous attempts to privately make peace with the Duke and Duchess of Sussex" but it has only resulted "in the other side wishing to air their repeated grievances to the world".
The late Queen issued an unprecedented statement following the Oprah interview, expressing her love for Harry and Meghan, with the caveat that “recollections may vary”.
Recent royal family tensions come amid another racism row at Buckingham Palace.
Lady Susan Hussey, William’s godmother, was forced to resign in disgrace after repeatedly questioning the heritage of a black domestic abuse campaigner at a palace reception.
The heir later said: “Racism has no place in our society.”
Kensington Palace said in response to Lady Hussey's remarks: "These comments were unacceptable, and it's right that the individual has stepped aside with immediate effect."
