Of all the issues around Brexit, immigration has probably received the most attention. It is probably the most politically challenging issue in the negotiations, and also presents numerous technical challenges.
The bulk of attention is on freedom of movement and what might replace it. A wide range of proposals are being put forward, often with divergent sets of principles and assumptions underlying them. Some have proposed maintaining a form of freedom of movement, perhaps with a temporary ‘brake’ mechanism if numbers become too high or restricting free movement to those who have a job offer, while others suggest bringing EU migrants into the regular UK visa regime. We are interrogating all of these proposals for their human rights compliance.
But this is also broader than freedom of movement. Why is it that many non-EU migrants voted for Brexit? Why is it progressives are so reluctant to bring EU migrants into the existing UK visa regime? The answer is that our immigration system, as a whole, is broken. If there is to be any merger of the EU and non-EU immigrant categories, the system itself must first be fixed.
