The function of the European Union has changed considerably since Britain last voted to retain its membership in 1975. That's why, after his re-election, Prime Minister David Cameron promised to give Britain a vote on the matter. On June 24, 2016, the UK will decide whether or not it will remain a part of the European Union. The EU referendum-or Brexit-as it has been called, raises many questions from immigration policy to free trade deals to issues of national identity. Twenty-eight countries currently make up the EU, which, at its core, functions to unite European countries into a "single market" as far as the exchange of goods and relocation of people. Former IMF official and economist Peter Doyle sits down with GLG to discuss what a potential Brexit would mean for the EU.
