If UKIP or the Tories or some combination of the two form Her Majesty's Government after the next election and they decide to implement Australian style immigration policies despite EU regulations against such things what would happen?
Going on the lack of action over France and Germany's flagrant busting of the Euro Stability pact stuff the answer would seem to be very little. In fact I think if I were a UK pol I'd be suggesting that if elected I would intend to govern Enlgand with no reference to Brussels what so ever including ripping up most of their ridiculous regulations. I'm sure there would be lots of bluster but I can't actually see any major action being taken because the rest of the EU wants to have British dosh.
