The Duke and Duchess of Sussex revealed their controversial decision on social media and, according to the insider, the move is a “declaration of war on the family”.
Charles is also reportedly "incandescent with rage” due to the lack of information – as is the Queen, who issued a curt, two-line statement following Harry and Meghan’s announcement.
"Discussions with The Duke and Duchess of Sussex are at an early stage. We understand their desire to take a different approach, but these are complicated issues that will take time to work through," the official statement read.
Taking to their Sussex royal account on Wednesday, Harry and Meghan wrote: “After many months of reflection and internal discussions, we have chosen to make a transition this year in starting to carve out a progressive new role within this institution.”
However, a source told The Sun that the Royal Family are said to be seething as the statement broke with official protocol.
“Their statement was not cleared with anyone. It breaks all protocol. This is a declaration of war on the family,” the source said.
“There is fury over how they’ve done this without any thought for the implications for the institution.
"The Queen is deeply upset. The Prince of Wales and Duke of Cambridge are incandescent with rage,” the source added.
