Theres probably a thread on this already but I've googled it and I can find it so here goes
At royal occasions (like today on the river) where the queen and 'the rest of the royal family' attend there's always the same faces (obviously!), the queen, Phillip, Charles and camellia, William and Kate and Harry but why is it always just them? Why not the rest of the queens children and grandchildren?
Is there a reason why Charles is the only one of the four there or is it simply because he is the oldest?
