I am old enough to remember the Diana years really clearly, including Charles & Diana’s wedding.
At the time I thought Camilla was awful “there were 3 of us in this marriage, so it was a bit crowded” said Diana, the media minx.
All 3 players, Diana, Charles & Camilla were victims of the protocols of the time, ie the future Queen needed to basically be a Virgin, & Charles & Diana basically had an arranged marriage, which just didn’t work out, but due to their position they weren’t allowed to quietly go their separate ways.
Charles & Camilla have —officially— been together over 20 years. Camilla has kept her head down & they look like a very happy couple.
I don’t know about the political ramifications of Camilla being queen or not. But as a person, she seems ok.
