UK Borders Bill

This has been very interesting. Until the Minister gave his explanation, I could not picture properly the scene that would emerge in the different parts of the United Kingdom when a suspicious person arrived. I think the Minister was saying that the risk-based approach is that when someone wishes to arrive from abroad they have to give notification that they are coming; the Home Office then looks them up to see if they are all right and then informs the port where they are to arrive. Is that, roughly speaking, what happens?
