It is unclear what roles the teenage grandchildren will play, but it indicates a close relationship with King Charles.
According to Palace sources, the Queen did not intend for her five grandchildren to hold the canopy over her during the ceremony.

Given the public scrutiny, Prince William and Catherine are still deciding what is best for their son.
Prince George's siblings are anticipated to attend, but the Harry's children will not.
