The UK will leave the European Union, most likely at the end of March 2019, two years after it invoked Article 50. Currently, the United kingdom has 73 seats in the European Parliament, representing England, Scotland, Wales, Northern Ireland and Gibraltar, but the question is what happens to these seats once the country leaves?
One option would be redistribution among existing member states. Since there is no predetermined formula, the redistribution has to be agreed on like any other change, through negotiations within the European Council. I doubt the EC has the time and energy for this before the 2019 European elections.
Another option, favored by the French president as well, is to create a new 73-seat European constituency. While I am sympathetic to this option, I think the most likely outcome will be the one of least resistance: leaving the seats vacant until new members join the EU, who then gradually fill them up.
It is from this scenario that the current visualization was born, as a means to explore which countries could join before the 73 seats run out. By using population numbers, I estimated how many MEPs a country was likely to get, and on somewhat subjective criteria, I added what I considered the most likely scenario.
The Western Balkans
While the Western Balkans are at different stages of accession, from opened negotiations to “not-candidate-(yet)” in the case of Kosovo, they seem the most likely states to gain membership in the near to medium future, and I think the EU is also very interested in getting them under its wing.
Given the way Turkish politics evolved in recent times, and adding to that the fact that many member states fear the addition of a Muslim state the size of Germany, one can safely assume its membership is frozen.
The Eastern Partnership
Things here oscillate between “impossible”, when it comes to Belarus and Azerbaijan, and “maybe, but not right now”, when it comes to Georgia, who made strong progress on its European path. I think smaller states such as Georgia, Moldova and Armenia might have an easier time getting EU membership than bigger ones, such as Ukraine.
Iceland, Norway and Switzerland don’t seem too eager to join any time soon, and Russia is both too big, too undemocratic and too confrontational to consider for this thought experiment.
