Prince Harry will not wear his military uniform or robes at his King Charles’ Coronation later today.
The Duke of Sussex served in the Army for a decade and did two tours of Afghanistan but will not be allowed to adorn the military uniform because he is no longer a working Royal.
The same rules applied when Charles' youngest son and Prince Andrew wore morning suits for the Elizabeth II's funeral last September.
Charles did permit Harry and Andrew to wear the uniform "as a special mark of respect" at the final vigil for the late Queen at Westminster Hall ahead of the funeral service.
The Duke made no specific requests concerning his outfit for the Coronation but was willing to wear whatever was asked of him, sources told the Telegraph.
It is reported that Harry will be relegated to the third row during the service at Westminster Abbey which will enthrone King Charles and Queen Camilla.
It is said he will sit between Princess Eugenie’s husband Jack Brooksbank and Princess Alexandra - the cousin of the late Queen, who hasn’t had a working royal engagement in a decade.
A source told The Sun: "There were discussions that the seating could be arranged on line of succession.
"But that would have put fifth-in-line Harry front and centre — and with William and Kate.
"Instead the decision was working royals only at the front and work back from there. Harry will be a long way from his father."
The self-exiled royal flew back into the country on Thursday ahead of the historic event.
Harry and Meghan wouldn’t confirm their attendance for weeks after they were invited until it was eventually revealed that only the Prince would make the trip across for it. Meanwhile, the Duchess of Sussex will stay home with their children, Prince Archie and Princess Lillibet.
The Duke is thought to be planning to leave just a matter of hours after the Coronation, flying back to America to be with his family. Charles' Coronation falls on what is Archie's fourth birthday.
The Order of Service for today's Coronation of King Charles and Queen Camilla has been revealed - and it confirms there will be no role for Harry.
The lengthy programme for the ceremony, which begins just before 11am at Westminster Abbey, shows which royals will be taking part in processions - as well as confirms the other key players taking prestigious roles later today.
The first sight of Charles and Camilla looks set to be around 10.20am when they travel in the Diamond Jubilee state coach to the Abbey from Buckingham Palace.
Members of the Royal Family are set to arrive at the Abbey from just after 10.35am to take their seats, while the Prince and Princess of Wales with their children Prince George, Princess Charlotte and Prince Louis will arrive minutes later and take their seats.
The main procession into Westminster Abbey by the King and Queen will begin just before 11am.
