I'm not all familiar with current law in the UK...
But, I bet there is a lot more power available to the "English monarchy" than is apparently believed by the average citizen. There is more to it than just being a "figurehead"
This piece covers quite nicely the powers of the monarch, and the actual practical truth behidn them.
Yes.
Constitutionally, the monarch's most important function is to ensure that the United Kingdom always has a government.
Under normal circumstances, this involves nothing more than accepting the resignation of the outgoing prime minister, and appointing the incoming prime minister, after a parliamentary election.
But the monarch would have considerably more discretion under abnormal circumstances. If, for example, the Prime Minister went insane, and the British government ordered its armed forces to invade Iceland and carry out a genocide of the Icelandic people, the Queen, as Head of State, could simply remove him from office, and appoint a sane person in his place. If terrorists set off a nuclear bomb in the heart of London, and killed every member of Britain's Parliament, the Queen could appoint a caretaker government and call for new parliamentary elections. If they got the Queen too, then the crown would pass at once to her heir. And so on.
In fact, the monarch's representative here in Canada, Governor-General Michelle Jean, was compelled to exercise her discretionary powers just recently.
At present, no party holds a majority of the seats in Canada's federal House of Commons. The leader of the largest party, Stephen Harper of the Conservatives, is prime minister, but must negotiate with the other parties to obtain a majority to pass legislation.
At the beginning of the year, Harper's government upset the other parties so badly that two of them formed a coalition, with the support of a third, and announced their intention to defeat the Harper's government on a vote of confidence. Faced with this prospect, the Prime Minister went to the Governor-General and asked her to prorogue Parliament--to suspend it, temporarily.
This was a really unprecedented situation. The Prime Minister's request for a prorogation was obviously selfish and politically-motivated. The Governor-General could have refused, and forced Harper to face the music in the House of Commons. But there were good arguments for granting his request anyway: the two parties who had formed a coalition, for example, actually controlled fewer seats than the Conservatives. So, in the end, she granted a prorogation.
Now, I am not a Conservative supporter, and at the time, I thought the Conservatives were being extremely disingenuous about the situation in Parliament. Their supporters, for example, were shrieking hysterically about a 'coup' and a 'threat to democracy'. One of my former students had befriended me on facebook, and invited me to join a group to "Say NO to the coalition--say YES to DEMOCRACY in Canada!" I bit his head off, and told him to learn how the parliamentary system actually works, and stop being such a drama queen. Needless to say, he hasn't spoken to me since.
But, in retrospect, I think the Governor-General's decision was probably the correct one. Had she refused the Prime Minister's request for a prorogation, Harper's government would have been defeated, and he then would have gone back to Rideau Hall and asked her to dissolve Parliament and hold an election. It would have been the same mess all over again.
Plus, I doubt if a majority of Canadians really wanted an election. And had one been called, it would have been held in a crisis atmosphere whipped up by Conservative disinformation and Quebec-baiting. Better to give Parliament a "time-out," and allow tempers to cool--which is what the Governor-General did.
If the UK's two major parties ever decline in popularity to the point that the British House of Commons becomes as fractured as its Canadian counterpart, the British monarch could easily find herself in a similar situation.
