Prince Harry's latest move to be ignored by King Charles and Queen Camilla

The Duke of Sussex's relationship has been strained with his father since he published his autobiography Spare in January 2023.

The paperback version of the controversial royal book is set to be released in the US on October 22 and in the UK on October 24.

A source told the Express: "It will be business as usual for the King and Queen during this tour and they don't want it to be marred by any talk of Harry's book.

"It's so insignificant to them at this point and they've got much bigger things to focus on.

"The King is keen for this tour to be a success and it [Harry's book] is not something that even registers on his radar."

They added: "This is a key visit for the monarch and he doesn't want anything to take away its focus.

"The fact that the King has put his treatment on hold to undertake such a gruelling trip is testament to how important it is to him and the monarchy."

It comes as King Charles was heckled during a visit to Australia’s Parliament House in Canberra for a Ceremonial Welcome and Parliamentary Reception.

Victoria Senator, Lidia Thorpe screamed at the monarch, who watched her without much expression.

Thorpe said: "You are not our King, this is not your land!"
