I too remember the wedding of Diana and Charles.....thinking what a beautiful fairy tale.....unfortunately having read since, about Charles and Camilla, and the fact that they were together the night before that wedding, when I see clips of their wedding now, I see Charles as a proper arsehole, and thats why it pains me to think that Camilla will probably be sitting where Diana should have been sitting at William's wedding. Dont they have any shame at all.
I believe the chair for the mother of the groom should be respectfully left vacant, and if its not I dont know if I want to watch the wedding.
