They are desperately trying to craft another brexit out of the Rwanda policy. Something that is generally misunderstood by the public at large, and can appeal to the base ‘small island’ mentality that still holds a lot of sway in our collective thinking.
I don’t think it will work, however, as the government is mistrusted on immigration from the outset. While the policy is popular (based on its miscommunication, not reality), it’ll be deemed a failure of an incompetent government, rather than ‘foreign courts’ or whatever spin they’re trying to put on it.
