The 96-year-old monarch’s great-grandchildren will likely also participate in the variety of events over the first weekend in June, but they will not all appear on the Buckingham Palace balcony as is tradition for Trooping the Colour. The palace announced last week that only working members of the royal family will appear for the balcony appearance instead of the full extended royal family.

Prince Williamand Kate’s three children are expected to be there along with Prince Edward and Sophie’s kids, Lady Louise and James, Viscount Severn.
