What you say may well be true, but the fact of the matter is that Prince Charles cannot command the level of respect that his mother does, or that his sons have the potential to.
As soon as he becomes King, every dominion except Britain itself will become a republic, and in Britain itself, I suspect republican sentiment will form the majority opinion and only apathy will keep the monarchy in place...
What's this? First I've ever heard of it, if it's true.
Are you saying that the United Kingdom will officially break up when (and if) Charles becomes King?
Elaborate, please.
It won't happen in Australia quickly either.
The Queen is more popular than the Prince of Wales, and there is probably a slight majority of support overall for a Republic in Australia even now. But to change the Australian constitution to allow for a Republic, one single model proposed at referendum has to get majority support. And that's not likely to happen in anything approaching the near future. There's at least three competing models, none of which can get more than about 30% support.
This is why the 1999 referendum didn't come close to making Australia a republic.
The process might be less convoluted in some other parts of the Commonwealth - but for Australia, it's not going to be a fast process at all.
