The article concludes that if Britain exits the EU immigration will only fall because of the resulting economic collapse.

I have always been and still am pro-Europe. I sense that for the UK to leave the EU would be an economic disaster. On the other hand, the UK is right to look to protect the UK’s interests. After all, France, Germany and Italy have a long history of profiting from the EU.

Thoughts?
