Master of its own fate, the British nation, in the exercise of its exclusive sovereign powers, decided through the vote of its people, to withdraw from the European Union. Therefore, the United Kingdom willingly embarked on the tortuous path of Brexit and, after years of negotiations and controversies, achieved its target: to quit its EU membership and all that comes with it. While the British Government’s compliance with its people’s will is not under scrutiny, concerns arise over the terms and conditions of the withdrawal arrangements and the eventual costs (not merely economic) Britain will now have to bear.
