Supranationalism in Europe

The European Union has been the largest experiment in supranationalism in the history of the world. This attempt to unite over 500 million people under the umbrella of the EU has brought benefits to its member countries, but it has also come with its burden of costs. The tensions caused by membership were recently highlighted when the United Kingdom voted to leave the EU. For this forum, find an article about a particular aspect of EU policy, such as economic policy, immigration policy, environmental policy, or agricultural policy, and discuss how that policy has caused tension between the EU and between member nations. What effect do you think these tensions will have on the future of the EU?
