The Queen has a lot more powers and duties and most know. See https://en.m.wikipedia.org/wiki/Monarchy_of_the_United_Kingdom For example, she appoints the Prime Minister and is Commander in Chief of the military.
Sorry, meant “than most know.”

Ah, but what would happen if she didn’t appoint a Prime Minister who has a majority in Parliament? And what would happen if she didn’t commit the armed forces to something already approved by Parliament?
I actually don’t know. But I suspect that the consequences would be so severe that she’d dare not do it. And if you dare not do it, do you really have that power in the first place?
