When I was growing up in England, I would never have imagined where I am today. For this, I can thank only the policy of freedom of movement, a founding principle of the European Union. It is a policy that since the victory for Brexit in the EU referendum has come under sustained attack. It has, at worst, been described as the potential cause for the breakup of Europe, and at best a bargaining chip, a necessary evil in order to secure access to a free trade area. Far from being a negative and destructive policy, freedom of movement is Europe’s greatest achievement, its most hopeful idea, and the policy that provides incredible opportunities to all.
