My Lords, the flow of migration, unless obstructed, is rather like the flow of water—it finds its own level. The Bill is, of course, intended as an obstruction to that level. To take my water analogy, the Thames Barrier is a necessary obstruction to prevent the flooding of the City of London. We read in many assessments that the number of people who will potentially come to this country is now over 100 million. The number who can come is obviously limited by the capacity of the country to absorb them, either temporarily or permanently. The natural level at which migration will find itself, if not impeded to a level that meets the capacity of a country, is when the standard of living that a country can provide has been diluted to a level so close to the
country from which people want to come that the journey is no longer worth the risks, hazards and costs of undertaking it.
That being said, what is absolutely clear is that the Government have made a huge mistake in choosing Rwanda. Why Rwanda? We have heard from the right reverend Prelate what a good place it is, and I absolutely accept that. But Rwanda is a small, landlocked country in Africa which is a tenth of the size of the United Kingdom and has a population density that is double ours. The United Kingdom has 278 people per square kilometre and Rwanda has 569. Can the Minister reveal to us the process of thought by which the Government came to the conclusion that they would even suggest Rwanda as a suitable obstacle to try to get to the right number of people whom we can absorb.
Some of your Lordships may remember that, in 2015 and 2016, I put forward an alternative plan, again to address the obstacle of finding another country. I said that we needed a very big country that had a desert and was very underpopulated. I suggested that the migration problem was a global problem that must be dealt with by the United Nations. I suggested that—and bear in mind this was several years ago—perhaps Libya might meet that aim. I thought that an area of desert could be negotiated by the UN to which everyone would go and there it would be determined whether they went where they wanted to, or went back where they came from, or whatever. The population of Libya is four people per square kilometre. I do not say that Libya is suitable now, but I cannot understand why the Government are persisting with Rwanda, since it is obviously wholly impractical. I hope the Minister will address that point.
