Yes, he is - unless he predeceases the Queen, he will be the next King, with Camilla as his Queen Consort. Then William is next, with Katherine as his Queen Consort. Then George, who is still a small child at this stage.
Parliament can alter the order of succession (the Queen cannot) but is extremely unlikely to.
Given the Prince of Wales is already in his 70s, his reign may be short, so many are already looking towards the next generation.
No doubt many wished Charles and Camila could just be skipped over and go straight to William and Katherine.
Charles is a total Globalist and Environmental nutcase as I see it. And Camila will always be seen as the other woman that came between Charles and Diana.
Love your home page. May they all rest in peace.
His genes come from two parents who lived to be in their mid (Queen) to late (Prince Phillip) 90's. He'll probably reign at least 10 years or more.
