Sarah Montague is in Brussels to talk to the man with the unenviable job of finding a way out of Europe's financial crisis. He is Olli Rehn, Europe's Commissioner for Economic and Monetary Affairs. It's nearly two years since the Greek crisis first blew up; and in that time seven heads of Eurozone governments have been replaced; there have been at least 15 European summits; and any number of plans; and yet, Greece is still on the verge of defaulting and the German Chancellor Angela Merkel has warned this coming year will "undoubtedly" be harder than the last. What has been achieved and are we any closer to resolving the crisis?(Image: European Union Economic and Monetary Affairs Commissioner Olli Rehn. Credit: Reuters)
