A few people will be lost to UKIP etc, but the general election system is so overwhelmingly skewed towards needing to vote for one of two parties that we'll all fall yet against into a 'lesser of two evils' vote. The British public has proven time and again that it won't lift itself out of apathy to stop things that aren't in their interest, and the establishment has similarly proven its ability to get what it wants, even in the face of overwhelming opposition from everyday people. If it isn't free movement, it'll be something so similar that a close look will find it hard to spot the difference. They'll name it something different, naturally, but a rose by any other name...
Anyway, I didn't mean in terms of popularity, I meant in terms of feasibility - it will be far easier to implement socialist reforms outside of the European Union from a legislative standpoint. Perhaps that aforementioned apathy can be (and may NEED to be) utilised; I'm sure the public would love to watch a revolution over their TV dinners.
