It is expected that the Prince of Wales will have a prominent role in the coronation - and after Prince Harry's dramatic account of their falling out there will be attention on the two brothers being seen together again.
Prince Harry's memoir described a physical altercation between the brothers and arguments about their father marrying Camilla.
The Queen Consort's grandchildren will be among the children with roles at the coronation, and Buckingham Palace has said that after that event will be an "appropriate time" for her to become known as Queen Camilla.
