I am grateful to my hon. Friend for the historical point. In response to what Jack Brereton said, does my hon. Friend recognise, as I do, that freedom of movement was actually brought in to replace the extremism of Soviet communism and Nazism? It is one of the greatest achievements in history—economically, diplomatically and culturally. Is it not a great shame that people such as the hon. Gentleman can see it go so easily and cheaply?
