CONstitutional matters

I would have to thank the recently departed constitutional warrior, Elizabeth Beckett for the following information:
At her coronation, the Queen Elizabeth the Second swore on oath to 'rule this country according to our laws and customs. This contract with us was written clearly in Magna Carta and replicated by Edward I in 1274.'
On six occasions monarchs have returned bills to Parliament on the grounds of them being unconstitutional since 1707 in the time of Queen Anne, the last monarch to overturn a bill in his/her own right.
George the Fifth considered the passage of bills to be a 'formality' but 'automatic assent' is nonetheless, unconstitutional.
Tragically, the Queen should have been the last bastion against takeover by alien governments and had no entitlement to allow any of the laws, customs and constitutional rights to pass to the European Union. She caved in and the 'fudge' has been a disaster for our constitution which is full and as complete as could be.
Our constitution has not been one put into place but has evolved over centuries only to be destroyed in a few short decades. Contrary to the claims of some that we do not even have a constitution, we have the most developed one in the world - it is only that it has never been codified.
I am no republican and the thoughts of a Head of State who is a politician revolts me, I am finding it increasingly difficult however, to consider myself to be even a luke warm monarchist.
