I am not sure how my noble friend’s two points tie together. He talks about an identity number, and of course a national insurance number is a form of identity number. Certainly it proves a person’s right to work in this country. I am not sure how a separate national identity number would add to the mix; nor am I sure how my noble friend thinks that national insurance numbers are corrupt, unless he is saying that they are used corruptly, but I am sure that the same would also potentially be true of national identity numbers.
