That question does not merit an answer.

Under Labour today, a national insurance number can never be proof of anyone's right to work, as the hon. Member for Epsom and Ewell appears to believe and as he implied this afternoon. The previous Conservative Government believed that it should be and legislated to that effect. That is a crucial point. The Tories thought that a national insurance number should be a passport to work and legislated to that effect. I repeat that, under Labour today, the national insurance number on its own cannot be an automatic passport to a job. It is an administrative mechanism whereby we can track people's contributions to the national insurance system and record their entitlement to pensions and other benefits.

Of course, when the Conservatives were in power, illegal immigration and working were not the global phenomena they are now. That was not because they had well thought out policies to keep them under control. The main reason was that, under their stewardship, the economy was going to hell in a handcart. No one, especially not the 3 million unemployed, associated Britain with work.
