Greece’s ongoing debt crisis and governmental instability has become the focal point of this week’s G-20 summit in Cannes, France. A day before a scheduled no-confidence vote in Greek Parliament that could lead to the government’s collapse, two ministers have publicly split with Prime Minister George Papandreo over his plan to hold a referendum on a European bailout plan. Finance Minister Evangelos Venizelos and three other ministers are now opposing the referendum, saying Greece’s membership in the euro cannot be jeopardized. Gavin Lee, correspondent for the BBC, and Rachel Donadio, Rome bureau chief for The New York Times, report on the latest developments.
