The departure of any country from the euro zone would be a warning sign for Europe, one of the European Central Bank's top officials said on Wednesday, adding that he expected Greece to stay inside the currency bloc. "I refuse to discuss a Greek exit from the euro area because we are not working within that framework," Benoit Coeure, a member of the ECB's Executive Board, told French publication La Croix. "We are financing the Greek economy and we are working alongside the IMF and the European Commission to secure an agreement with Athens, with the aim of keeping Greece in the euro area," he said.
