BELGIUM-EU-DIPLOMACY-SUMMIT

European commission member in charge of Brexit negotiations with Britain, French Michel Barnier listens during a sesion to brief European commissioners on his preparations for the EU withdrawal talks on March 22, 2017 at the European Parliament in Brussels. Britain must reach a deal on what it owes the European Union before talks can start on a post-Brexit trade deal, the EU's negotiator Michel Barnier. "When a country leaves the union there is no punishment, there is no price to pay to leave. But we must settle the accounts, no more, no less," he said in Brussels.
