ROUGH CUT NO REPORTER NARRATION<br/> <br />Leftist SYRIZA leader Alexis Tsipras cast his ballot in Greece Sunday where election results could upturn financial markets the world over.<br/> <br />Tsipras, who is threatening to tear up the terms of the country's 130 billion euro (163.75 billion U.S dollar) bailout, wants to renegotiate the deal.<br/> <br />His opponent, establishment heir and New Democracy leader Antonis Samaras, however, says rejection of the EU/IMF bailout would mean a return to the drachma and even greater economic calamity.<br/> <br />The election is too close to call and could push the debt-ridden country out of the European single currency, rocking the euro to its core and sowing turmoil in global financial markets.<br/> <br />A Greek exit from the single currency would heap further pressure on two far larger European economies - Spain has already received up to 100 billion euros to save debt-riddled banks and Italy could be next to seek a bailout.
