"privalage"???
(apologies for joioning the spelling police, but really?)
HRH is privileged, and is not simply an RAF officer - get over it?
Would you really want the "head of state" per France, Italy etc - though the lovely Carla B does add a cetain something!!
We have a constitutional monarchy, and a constitution that, though no longer truely "unwritten", serves us well. I remind myself of the grant of our Commissions, and of the Colours that are proudly borne. Not out of some sense of feudal obeisance, but because such things represent a sense of history and continuity, and a deep respect for those who have have gone before.
Republicanism?! Even the staunchest socialists couldn't decide how to reform the House of Lords!
I for one will enjoy the Bank Holiday, and raise a congratulatory glass or several !
