Greece's decision to call a referendum on the demands of its creditors does not excuse it from paying its debts and euro zone ministers are now discussing what to do now Athens has rejected a cash-for-reforms deal, Jeroen Dijsselbloem, the chairman of the euro zone finance ministers, said on Saturday. "It is a responsibility and it doesn't go away." "We will have a second meeting to discuss any consequences from the political conclusion just drawn and to prepare for whatever is needed to make sure that at all times the stability of the euro zone remains at its high level," Dijsselbloem said after a first Eurogroup meeting concluded.
