Borders, Citizenship and Immigration Bill [HL]

The Minister says that this will not mean that you will have to go through two checks but I cannot quite understand how it is going to work. I see that it would be really nice if it was streamlined, but actually you come in, the UKBA person looks at you, does all your details, looks at your passport, and then you go and collect your luggage, and then you go past the other people. It is not going to be possible to do all that at once with one official, is it?
