Hon. Members will know that permanent residence is an EU law concept similar to, but not exactly the same as, indefinite leave to remain in the UK for non-EU citizens. It is not guaranteed that the concept itself will continue to exist after we leave the EU. However, we are not debating today the complex legal issues that arise in this area; instead, we are debating a principle. We are debating how the rights associated with permanent residence are to be guaranteed.
