King Charles, meanwhile, made a rare comment on claims made in books.
Buckingham Palace did not ignore a shocking claim in a book by Earl Charles Spencer.
This is, however, extraordinary, given the perception that Buckingham Palace rarely weighs in on claims made in books.
Now, a spox from the palace issued a statement, saying, "While we do not comment on books as a matter of principle, His Majesty is mindful that the pain of fraternal grief can cloud reason, affect judgment and colour memory in ways others do not recognise, even many years after such a loss."
The response, in turn, attempted to cast doubt on Spencer's characterization of his conversation with Charles about Princess Diana's death, in which he allegedly said, "We'll forget her soon enough," which he recorded in his book Swan Song.
