I am referring to a hypothetical scenario where parliament tries to make the heir to one of the alternate successions to the English throne the monarch. I know that Queen Elizabeth has royal prerogatives of giving Queen’s Consent to allowing the debate of bills affecting the interests of the crown(and there are examples of when she has withheld consent), and gives royal assent to bills(although 1708 was the last time a monarch vetoed a bill, she would likely veto a bill that changes the monarchy)
The catch is that the 1708 veto, and the times the monarch withheld consent was done acting on the advice of ministers. Does that mean that she cannot withhold royal consent and assent against the advice of her ministers?
The monarch also has the rarely used power to appoint and dismiss ministers, so would she be able to dismiss ministers before withholding royal consent and assent or does she have to give consent and assent right when the bill comes to her?
