The idea that Mrs. Windsor represents Britishness is out of this world!
As "heasd of State" of 14 countries, and "head of the commonwealth", and "head of the Anglican Church" from England to South Africa (bishop. Desmond Tuto is a member of the Anglican Church), she has too many heads at stake to be "British".
This mania of being the head of half the world's population is hardly a representation of the average British person signing on, or shuffling to work in a Morris Minor, or claiming somesort of benefit to have the weekly pennies
