Nationality and Borders Bill

How does case-by-case work? If we are not going to have agreements and the Minister says it is much better to do it case by case, how does that work? The diplomatic post in the capital in question goes in and says, “We have Mr X in an accommodation centre in Kent. We’d like to send him to you because we think he has a connection to you and we don’t want to let him have asylum here.” What happens if the country in question says, “Well, if he’s with you, he’s your problem”? Do we just put him on a plane and tell him to take his chances at the other end, or are we negotiating his terms of entry into the third country?
