What on earth are we to call it when we lisp to our great grandchildren about this Day of Days?
Taking the long view, I look back to the Anglexits of the sixteenth century; under Henry Tudor in 1533 and Bloody Bess in 1559, which, precursors of today's Brexit, freed England from tyrannical foreigners (not to mention their Detestable Enormities) and led us into Broad Sunlit Uplands.
We Took Back Control!!!! Today, under our great Leader Boris, we are simply completing what the Tudors so magnificently began.
Both Anglexits involved Anne Boleyn alias Bullen ... the first, in 1533, because Tudor rather fancied getting inside her farthingale; the latter, in 1559, because Boleyn's daughter, proclaimed a bastard by her father, had taken possession of the English and Irish thrones.
So let's call it BULLENDAY!
You know it makes sense!!
