Parliament pays their wages.
Or is it the queen that pays Parliament?
HM Revenue and Customs is a non-ministerial department.
HMRC (Her Majesty's Revenue and Customs) was established by the Commissioners for Revenue and Customs Act (CRCA) 2005, which gives the legal powers and responsibilities of the department to Commissioners appointed by the Queen.
I'm not really a fan of the Royal family myself. The royals clearly are not like the royals from a couple of hundred years ago where they had absolute power, they still seem to have a fuck load of power though. It's never used though which makes people think they are there for ceremonial purposes.
The thing is, if the queen wanted to get involved in shit, at the very least its going to make things very awkward for the government. She still holds a lot of influence.
One other little thing, its probably meaningless but I'll put it out there. All MP's must take an oath before they are allowed to take their seat in Parliament.
I... swear by Almighty God that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth, her heirs and successors, according to law. So help me God.
Members who object to swearing the oath are permitted to make a solemn affirmation under the terms of the Oaths Act 1978:
I... do solemnly, sincerely and truly declare and affirm that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth, her heirs and successors, according to law.
The above oath is not optional, they can take it under protest, but they must still take it.
Also the following positions require an oath to the Queen.
And then of course you have the likes of the uniformed forces that must take the oath as well as people wishing to become UK citizens. Even scouts and girl guides take the oath.
I guess any government that seeks to remove the Monarch would be guilty of treason. No government will ever attempt to remove the Monarch unless they had overwhelming public support to do so, essentially it would mean a revolution. Since 76% of people in the UK like the Monarch, a revolution is highly unlikely for the foreseeable future and certainly not as long as Queen Elizabeth II rules.
