neither in nor out...
It's been a while coming but it seems as if the Brits are not happy with the EU. Of course, there was always the deep rooted suspicion of "foreigners" eg those who live across the Channel. It is hard for them to accept the concept of a system that operates fairly smoothly without class. Unfortunately for Mother England, class still exists, maybe not as pronounced as previously but still prevalent.
Now the British have developed a taste for French wine, French cheese, German cars and spaghetti but that's enough of a good thing. The pretty little houses en Provence and in Espana are also all part of the deal but again, enough's enough. The wealthy ones are sitting pretty. Now is the time to get serious.
Unfortunately for the "Continentals" the British also also fairly rigid in their concept of rules and how things ought to be done. Hence the finger pointing at the "PIGS" ( Portugal, Italy, Greece and Spain) whose system of book-keeping is somewhat akin to gambling. The Germans and Dutch are pretty rigid but somehow manage to function without treating blue or white collar workers as troublemakers. There's a gap as wide as grandma's bloomers between the divisive Anglo Saxon philosophy and the more inclusive European system.
Having narrowly survived the eventuality of Scotland leaving the Union, the UK is now paying the price of many wealthy nations with refugees ,both economic and political, flooding their shores. It's compounded by the old colonial outposts now wanting a piece of the action and repayment for wealth extracted.
When voting regarding EU membership comes along who knows what will happen?. In the meantime the UK is taking a much harder line with refugees , much to the chagrin of the EU.
