My hon. Friend makes an important point. I will come to it in a moment. I should like to hear from the Government about the migration that they foresee taking place under the provisions. Let us remember that such migration carries with it the right to settlement. The system is called “work permits”, but it is work permits with the right to settle. We are not talking about the number of people coming from eastern Europe; that is a different issue, which is dealt with under European Union treaties.
