CTL, absolutely incorrect.
Camilla WILL be Queen (unless she or Charles passes away before Queen Elizabeth). As wife of the future King, by law of both the UK and all Commonwealth nations, she is currently the Princess of Wales and will be Queen upon Charles’ ascending to the throne. Period. Whether she tells the newspapers to call her Queen or Princess of Wales or Duchess of Cornwall or HRH The Princess Consort or any of whatever the MANY titles both she and Charles have, is an irrelevant personal preference of either hers or the newspapers.
But no matter what you or others (even she!) likes or dislikes, Princess Camilla is now Camilla, Princess of Wales and will be Queen Camilla once there is a King Charles.
As far as the divorce issue, don’t forget that their zeida King Henry specifically broke the Church of England away from Roman Catholicism so that he could remain King and get divorced. So they surely have ample precedent. (And like adulteress Diana, two of his wives were beheaded for adultery, which he – like Charles – was also guilty of.)
