If the UK quits the EU, it will be because British politicians have pandered to anti-immigrant sentiment rather than addressing the supply-side failures that drive it.
If Britain votes to leave the EU it will be because of hostility to immigration. It will not be because of the threat of eurozone caucusing, the role of national parliaments vis-a-vis the European Parliament, regulatory threats to the City of London or concerns over the competitiveness of the EU economy. Disillusionment with the EU has risen in the UK because membership has become synonymous in many voters’ minds with uncontrolled immigration. Why has immigration, in particular EU immigration, become so toxic an issue in the UK that it could cost the country its membership of the Union?
