Millions of Greeks vote on EU bailout

Greeks began voting in a referendum on Sunday that presents the biggest challenge to the euro since its adoption  and is already sending shock waves through the world’s financial markets. First results are expected at 9 p.m. PM Alexis Tsipras urged voters to cast a no ballot at a rally in the centre of Athens on Friday night. He assured them it would not be a vote for leaving the euro, but for remaining in Europe “with dignity”.Greece’s creditors and most of the opposition parties have claimed that, on the contrary, it could lead to Greek’s exit from the single market (“Grexit”) and even the European Union
