Can the Queen pass on the throne before her death?

For some reason there has been considerable speculation regarding this issue. The simple answer is yes. There is no obvious reason why anyone other than Charles should become King when Queen Elizabeth II leaves the throne. Charles himself has expressed no wish to refuse the Monarchy, and it seems that the whole question is a matter of wishful thinking on behalf of those who find Charles' somewhat quirky and whimsical personality unseemly for a King of England.
