"sensible conversation about immigration"

Article by Oxford expert who has written a book on the subject. His evidence is, of course, in the book (Allen Lane, £20). Covers a lot of things like spousal visas and skilled v. unskilled.

Has this gem included which is a bit much to put into any article supposedly introducing a 'conversation':

"These ten building blocks are not incontrovertible truths but the weight of evidence favours them to varying degrees. If your views on migration are incompatible with them, they rest on a base too fragile for passionate conviction."
