PRINCE HARRY’S TELL-ALL BOOK LIKELY TO SEE HIM SIDELINED FOR THE QUEEN’S PLATINUM JUBILEE BASH

The Duke’s memoir — due out shortly after the party — is threatening to widen the family rift and put the royal celebration in turmoil.

Royal sources say it will make it “impossible” for him and Meghan to attend.

The Duke, 36, surprised dad Charles, 72, and his brother William, 39, by revealing he was writing a book about his life.

Royal insiders fear it will go further than his Oprah interview, in which Harry, 36, and Meghan, 39, branded an unnamed family member as a “racist”.

Palace sources said: “Everyone now thinks it is inconceivable that he and Meghan can be part of the Platinum Jubilee.

“Bringing it out in 2022 when the Queen is celebrating will dampen the party.”
