I am not a great royalist and cannot imagine the royal family surviving another 50 years unless it changes. When the queen dies the English royal family will be in mortal peril. No, I think what was really being mourned was the end (or very near end) of an era.
Privilege, as a result of who you are, will end. Minor royals who live wealthy lives off UK taxpayers will end. I think the royal family has to evolve. I cannot think of a suitable president should we become a republic. No, I think we will still have a royal family, but very different.I feel very sorry for the queen who has lost a lifelong husband and companion. They we married for 73 years, which is a long time!
