European Council President Donald Tusk told Greek Prime Minister Alexis Tsipras on Monday that he saw no willingness among member states to agree to Tsipras's request to an extension to bailout loans. "After consultations with the leaders, in the absence of new elements, I see no willingness to go against the positions expressed by finance ministers at their June 27 meeting," Tusk said in a letter seen by Reuters that was sent in reply to request from Tsipras for a one-month extension of credits. The letter reflected a closing of ranks by EU leaders after Tsipras called a referendum on the creditors' offer of cash for reforms and urging Greeks to reject it next Sunday.
