Eman, the royals are the UK's problem, and they do seem to be a problem. Can't for the life of me why you don't tell the whole lot to get off the dole and find paying jobs. Bug
The Queen has ultimate power over Parliament. Let's suppose that a government lost a vote of confidence in the House of Commons, but
refused to resign. A great deal of government business is done using the Royal Prerogative, which does not involve going to the House for approval, and thus the government could easily continue its business; declaring war, for instance. However, if the Queen commanded that Parliament be dissolved, then Parliament would have to be dissolved. The same situation might occur were a government to decide to cancel any and all general elections.
The Queen may also refuse to give her assent to a Bill recommended by both Houses. Royal assent has not been refused since 1707, and
it is not clear quite what would happen if the Queen refused consent today; in theory however, the Bill could not proceed into law.
Elected officials can be corrupted, and it's a good system to have a monarch who theoretically should be apolitical and reserves the power to step in during a crisis like, say in Germany in the 30's. where a weak government gave dictatorial powers to the elected chancellor. Not much chance of that in Britain where the queen could simply dismiss the lot of them.
They cost too much. I say follow the French example
Yes and France has been a model of stability ever since,hasn't it? You did get rid of the Monarchy once but had the common sense to bring it back with the understanding they would behave themselves. Since you have such admiration for Cromwell, why don't you marry him?
