Nick Clegg has said that Britain's economic recovery is dependent on immigrants:
The majority of people who come here work hard and make a contribution. Many have served - and still serve - in our armed forces.
And if every member of an immigrant community suddenly downed tools, countless businesses and services would suffer.
The NHS would fall over. And in a globalised economy, where talent is as mobile as capital, no nation can succeed by pulling up the drawbridge.
