The Prince and Princess of Wales’ three children are all expected to take part in the procession from Westminster Abbey which will follow the King’s coronation on May 6.
Prince George, Princess Charlotte and Prince Louis are likely to accompany the King and Queen Consort as they leave the Abbey after the service, the Times reported.
The children are expected to join their parents in a carriage behind Charles and Camilla who will travel in the Golden State Coach as they return to Buckingham Palace.
George will be nine and Louis will be five while Charlotte will turn eight just four days before the coronation.
George, who is second in line to the throne, and Charlotte attended their great grandmother the Queen’s state funeral at Westminster Abbey in September.
Prince Louis was not present and is thought to have been considered too young to attend the service with his parents William and Kate.
It is understood the Prince and Princess of Wales are still considering what roles George, Charlotte and Louis might play on the day.
The children’s attendance at public events is not normally confirmed in advance, particularly for Louis because of his age.
Kensington Palace declined to comment.
The royal children delighted crowds when they showcased their royal waves as they celebrated their great-grandmother the Queen’s Platinum Jubilee last year.
They made an appearance on the palace balcony for the flypast which prompted some comical reactions from Louis who held his hands over his ears, probably due to the roar of the aircraft overhead.
Louis also shared a sweet moment with his grandpa when he sat on Charles’ lap during the Jubilee Pageant as the parade passed by the royal box on the final day of the celebrations.
The Times reported that current coronation rehearsal plans do not suggest the Duke and Duchess of Sussex or the Duke of York are expected to take part in the procession.
The newspaper also reported that Harry and Meghan’s children Prince Archie and Princess Lilibet had not yet been invited to the coronation.
The date of the coronation will be Archie’s fourth birthday while Lilibet does not turn two until June 4.
