Just my opinion, but after the disgrace of Edward V111, I don't think any heir to the British throne would even consider the 'A' word.
Yeah, well, after Henry VIII no royal ever would consider divorce either....the times they are a changin'!!
Since they are accepting divorce and the married/divorced mistress as consort, it is time to consider accepting abdication as well.
Charles should finally marry the woman he has always loved. But, because they both are adulterers, neither should hold the title, "Royal Highness". They have hurt so many people, and thus are very "low" indeed. Charles should never ascend to the throne.
