CORONATION SHOWDOWN!

It's official Prince Harry and Meghan Markle will be forced to watch King Charles III's big day from the sidelines

The lineup is all set. After their official coronation ceremony at Westminster Abbey on May 6, King Charles and Queen Camilla will ride in the Gold State Coach during a procession through the streets of London back to Buckingham Palace. And, according to recently leaked documents, Prince William, Kate Middleton and their children, Prince George, Prince Louis and Princess Charlotte, will be in the carriage behind them, followed by Princess Anne and her husband, Tim; Prince Edward and his wife, Sophie; and four of the late Queen Elizabeth's cousins. “This event has been meticulously planned with Charles getting the final say, of course,” a royals source tells In Touch. “Working royals only are front and center.”

Which means Prince Harry and his wife, Meghan Markle, have been relegated to common spectators. “As nonworking royals, Charles is putting them in the same box as Prince Andrew — they won’t be part of the procession, nor will they stand on the balcony with the rest of the family when they reach the palace,” says the source, revealing that Charles, 74, alone wasn’t responsible for this decision. William, 40, and Kate, 41, convinced him that Harry, 38, and Meghan, 41, are “troublemakers and should be cut out. And Charles listened. This is so humiliating for Harry and Meghan.”
