Could Queen Elizabeth take her son out of the line of succession and make William the heir?

That's a more difficult one. Our constitution is unwritten, and in the past when such cases arose they tended to be sorted out on the battle-field :-)

It is pretty much inconceivable that Her Majesty would do so without the consent of both H.R.H. Prince Charles, and H.R.H. Prince William; additionally the Prime Minister (and probably those of the various Commonwealth countries which share the monarchy). In that case a bill wouldalmost certaily pass through Parliament (I suspect that it would be unopposed, except by a few arch-leftists who take any excuse to attack the monarchy), which would (like all bills) require Royal Assent, and then become law.

Don't know if you get MSNBC there (probably not, about six people watch it here, unfortunately) but Charles Sabine from London was just on with Don Imus (the best morning program - EVER!). They were discussing this issue and after the exchange ended, Imus' producer, Bernard McQuirk, asked Imus if he wasn't related to Camilla. There is a slight resemblance.
