“Elizabeth doesn’t “rule”, she has no real power. Her position is largely ceremonial and traditional”
Yes and no. The “Royal Assent” to bills passed by Parliament is a mere formality, but she does have the option of refusing to sign them. In this case there would be a showdown and she could essentially be fired from her job by the government. It’s the kind of thing that she would only do in the most dire emergency, like a coup d’état. King Juan Carlos of Spain had to do it once, and saved his country by doing do.
Yes...from what I have read, if she refused to sign any of them, it would be considered a huge scandal. She remains politically neutral (officially).
