Athens (AFP) - Two exit polls after a Sunday referendum in Greece on whether to accept tough bailout conditions suggested a narrow 'No' vote had won, potentially jeopardising the country's membership in the eurozone.A poll by the Star television channel gave a 49-54 percent range for 'No' ballots against 46-51 percent for 'Yes', while the Mega channel poll suggested a 49.5-53.5 percent 'No' vote and 46.5-50.5 percent for 'Yes'.The radical left government of Prime Minister Alexis Tsipras had lobbied for a 'No' result in the referendum in a bid to strengthen its hand in negotiations with international creditors.Join the conversation about this story »
