Yes, I agree that Camilla’s sister (and the other lady attendant, not sure of her name, but I assume they are both the two ‘ladies-in-waiting’, not that they are called that), were given quite a lot of air time.
But perhaps that is to show how much more ‘equal’ Charles wants the new monarchy to be? The late Queen was very much the main event, yes Prince Philip was her greatest support and sounding board, but she was definitely first and foremost. As is the King, but he is at great pains to include Camilla always.
It’s joint pictures on anniversary cards sent out to the public, it’s ’my darling wife’ frequently mentioned….
Camilla’s family are obviously hugely important to her, and I think Charles is very aware of that, , and wants her to be happy.
