There is unregulated immigration from EU.

Yes there is. That is not what ake said. It was only a few minutes ago but maybe a reminder would help.

Unregulated immigration from low wage economies to high wage economies is always wrong and ultimately harmful to both countries.

No mention of free movement of labour in the EU. It is the pure concept of someone encouraging unregulated immigration that sets people off on the 'let's blame the Polish fruit pickers' track. It is the language and idea of blaming the easy target that is wrong.

BTW - free movement of people within the EU works both ways. Have either of you seen the actual figures on how many Britons are living in Europe compared to EU nationals living here? Shall I give you a clue as to what those figure will be like or leave it up to you to assume the worst?
