The head of Greece’s main leftist party appears to have ruled out a coalition government with centrist groups in a split over the austerity measures and structural reforms demanded of Greece in exchange for the international bailout. Alexis Tsipras of the Coalition of the Radical Left has demanded that any potential allies reject the bailout in order to form a coalition government. But after talks on Tuesday, Tsipras said it is unlikely a deal will be reached. If no party has enough support to form a coalition government, another round of elections could be held next month.
