The Queen does not make laws, she just signs them off. She is also still the Head of State, on a voluntary basis, of a number of other countries including Canada, Australia, New Zealand etc. She is not ‘picked’ by politicians such as Merkel and Macron who may be gone next year. She has been a constant while 14 Prime Ministers and 13 US Presidents and innumerable other Presidents and Chancellors have come and gone. She has seen it all, entertained them all, and always did so for the benefit of the U.K. ... perhaps you would rather VDL or Michel from the EU. When you put your anti monarchy view to the side for a moment, you will see how lucky that the U.K. has been in having a non political Sovereign as Head of State.....or would you prefer Boris, Blair, Brown, Maggie or May.....
