The only time there was a major problem in living memory of the monarch not signing a piece of official paper was when Thatcher sent an armed force to evict the Argentines from The Falklands and the first the Queen heard about it was via the media.
The Queen is the head of the armed forces, she represents the UK and the Commonwealth on the Ferrero Rocher circuit and she ultimately is the focus of the nation's grief when it comes to war casualties.
So she summoned the PM to the Palace, made her stand on the naughty step and got the PM to explain herself.
It might not be democratic but if it were it would have won my vote.
Sorry Warb I failed to answer your earlier question.
Yes Scottish MPs do sit in Westminster but it's an awful travesty of democracy whichever way you look at it.
The last time Scotland turned in a majority for the Tories was 1959.
On the whole Scotland is a old school European style Socialist country.
Since 1959 there has been only one term of office that resembles that pattern and yet Scotland has been used as a policy lab testing out unpopular ideas like the Poll Tax safe in the knowledge that the government in Westminster has nothing to lose in terms of seats.
It would just make much more sense to have these two countries independent of each other but like any neighbour have treaties in respect to shared interests (like defending the shared island).
