Tory take on immigration is crazy

The incoherence of the Tories on immigration is truly breath taking - if they withdraw the UK from the European Union and the free movement of labour stipulations, the two million plus who have come, worked and contributed here will be forced to go home, The two million plus who have gone from here to work in countries like Spain and Germany will be forced to come home. The net result four million discontented people in countries where they don't want to be, without work. Surprising that we don't hear more from the business community about the ludicrousness of what the Tories/UKIP are proposing, as it will also mean huge losses for them?
