Earl Spencer felt it was his “duty… as an eyewitness to history” to write a new memoir chronicling the life of his sister, which has included a series of damning claims about the King.

It comes after the earl accused the King of gaslighting him after Buckingham Palace pushed back against explosive claims that Charles said “we’ll forget her soon enough” after Diana, Princess of Wales, died.
