摘要:On the morning of 24 June 2016, millions of EU citizens woke up to the news that the rights they took for granted for their very livelihood were not nearly as enshrined as they had previously assumed. The Brexit vote threatened the residency rights of the 3 mil- lion EU citizens in Britain as well as the 1.3 million British citizens residing in other EU member states. The result also reverberated around the 16 million EU citizens who in 2016 resided in member states of which they were not citizens. Britain’s decision to exit from the EU was born of a backlash against allegedly forced intra-EU migration, and it was assumed that the eventual Brexit to be pursued by the British government would involve a rejection of this aspect of European integration. Unfortunately for the British government, this aspect of European integration – freedom of movement – is one of the fundamental and inseparable four freedoms of the EU, and a rejection of any one of these meant a rejection of all four, and thus the all-important single market. Britain’s opposition to freedom of movement in the EU therefore has made a hard Brexit all but inevitable, and this is an existential threat to those who have chosen to take advantage of this freedom.
