Late Queen Elizabeth decided to hit back when she thought Prince Harry and Meghan Markle were trying to "cash in" on their royal links.
It was claimed by Robert Lacey, the author of new book on the royal family.
In the book titled "Battle of Brothers", he said
The decision made by the Sussexes to commercialise under their own royal trademark - "Sussex Royal" - prompted the Queen to put her foot down as the couple were acting without her permission.
According to UK's Daily Express, Lacey said: "Once again Harry had totally failed to consult the Queen about a major initiative affecting his royal work and image — and the image of the crown as a whole. The family finally hit back. Elizabeth II had always had a soft spot for Harry, and she had been delighted by the arrival of Meghan, whose personal energies seemed to complement her grandson’s so well. As Head of the Commonwealth and reigning over an ever more multicultural society in Britain, the Queen had especially welcomed the exciting new dimension that a mixed-race recruit brought to the Windsor identity — and as we shall see later in this series, she herself had spotted when things were going wrong, and had helped devise a strategy she firmly hoped would make things easier for the couple.
The author added, "But there were some matters on which Elizabeth II would not compromise — and chief among them was the authority of the crown.
He said, "By not disclosing their plans to market merchandise under their own royal trademark, Harry and Meghan had trespassed dangerously on that authority. To commercialise the crown required the crown’s consent — and the Sussexes had not sought that."
