I thank the Minister for his clear response. He refers to a cost of £2.4 billion. The best case scenario is a cost of £1 billion, and the worst case £3.5 billion, for a problem that the Home Affairs Committee struggled to find anybody, other than the Minister, to say was a really serious problem; even Migrationwatch UK was not that bothered. Given that we do not want to lose £2.5 billion from the economy, will he rethink these proposals?
