Princess Charlotte and Prince Louis will join King Charles III and Queen Consort Camilla in a carriage during the coronation procession.

Their roles in the coronation are still being considered by their parents, Prince William and Princess Kate.

It is unusual for young heirs to participate in the coronation ceremony, but this would be a break from tradition.

Camilla's grandchildren will hold a canopy over the Queen Consort during the anointing ceremony.

King Charles has a special connection to the Mount of Olives-made holy oil used for anointing, which is similar to the oil used in his mother's coronation.

Olives from Mary Magdalene Monastery, where King Charles' paternal grandmother is buried, were used to make the oil.

Despite their young age, Prince Louis and Princess Charlotte's participation in the procession is expected to be a memorable moment.

Prince Louis was not present at the Queen's state funeral due to his age, but his role in the coronation will be a historic moment.

The inclusion of the young heirs in the coronation procession highlights the importance of family and continuity in the royal tradition.
