Migration Statistics

Can I clarify what is being suggested here? I think that my hon. Friend the Member for Harwich and North Essex (Mr Jenkin) was talking about quadrupling the size of the international passenger survey. Is the right hon. Gentleman suggesting that, instead of quadrupling the survey, it should be made universal? If so, would we then not be talking about the count, and would there not be a better way of doing that than having a separate person with a clipboard asking questions?
