Its not exactly a case of lugging it is now...besides, can a Pole hold a British passport and a Polish passport?
Yes, of course they can.
The list of visa restrictions is tiny - apart from the big one, the USA, there really isn't much difference. In fact, if you like to go to more obscure places, it can be argued that a Polish passport is much safer.
And it's far more convenient to carry around a small card in Europe than to have to look after a passport. As for identifying yourself in Europe, the ID card is far more convenient than having to take your passport everywhere.
Plenty of hatred towards Britain in many parts of the world.
I can only but dream we will leave, but I think we all know this is never going to happen and even if we do, it wont make any difference, there are plenty of British companies around the world who have set up shop!
Well, having seen the way that the EU is policing the Eastern border, I wouldn't want to be stuck in the non-EU line. They are becoming *very* thorough in checking out non-EU citizens at passport control within Schengen - and I think most Brits would be utterly appalled to learn that they have to go through thorough checks just to go for a weekend to Paris.
Britain won't leave because she gains too much from it, no matter how people would like to twist it.
