BRUSSELS, BELGIUM - JULY 12: Slovenia's Prime Minister Miro Cerar arrives at the eurozone leaders' summit on the Greek crisis, at the European Council headquarters, on July 12, 2015 in Brussels, Belgium. Greece is teetering on the edge of default, cut off from bailout aid, in arrears to the International Monetary Fund (IMF), owing large debt repayments this month and fending off suggestions that it could soon exit the eurozone.
