Westminster Abbey has published the Order of Service for today's Commonwealth Day service, confirming which members of the Royal Family will attend and those missing it this year.
The annual celebration will be King Charles's first as Monarch, and he's set to move away from some of the traditions put in place by his late mother.
The King and Queen Camilla will lead the procession, followed by the Prince and Princess of Wales. Prince Edward, the new Duke of Edinburgh, and his wife Sophie, now the Duchess of Edinburgh, will be next before Princess Anne and Sir Tim Laurence.
