I shall be happy to provide the hon. Gentleman with the statistical authority that offered that figure to me. It is a Home Office figure that we used for planning purposes as we designed the programme that we are introducing.
My argument is that the Government should be held accountable for the sense with which they introduce the biometric immigration documents for the purposes we set out in the debates. I can understand the intention of the procedure that the hon. Member for Ashford proposes, and its ambitions, but its effect would be to slow down dramatically the speed with which we could introduce the systems and therefore the speed with which we could shut down illegal journeys and illegal jobs.
