The UK’s Home Office drafted plans for limiting immigration inflows from the EU Member Countries after Brexit. The leaked draft indicates that the Theresa May’s government adopted policy of the “Britain first’. The document explains it in plain language: “Put plainly, this means that, to be considered valuable to the country as a whole, immigration should benefit not just the migrants themselves but also make existing residents better off.” It, however, is not so easy to stop migration flows between the UK and EU. There are some 3.2 EU citizens living in the UK, but also 1.2 million Britons living in the EU. Any restrictions for the EU citizens in the EU would likely provoke response from the European governments. Moreover, some UK’s industries heavily rely in migrants’ labour (agriculture, hospitality sector, manufacturing, nursing homes). The EU also may consider introduction of trade and custom barriers after Brexit.
