ATHENS, Greece (AP) — A Greek state TV exit poll is projecting that anti-bailout party Syriza has won Sunday’s parliamentary elections — in a historic first for a radical left wing party in Greece.

But it’s unclear whether Syriza has won a decisive enough victory over Prime Minister Antonis Samaras’ incumbent conservatives to govern alone. For that, they need a minimum 151 of parliament’s 300 seats.

The centrist Potami (River) party is battling for third place with the Nazi-inspired, extreme right-wing Golden Dawn, whose leadership is in prison pending trial for running a criminal organization.

Syriza leader Alexis Tsipras has promised to renegotiate the country’s 240 billion-euro ($270 billion) international bailout deal. He has pledged to reverse many of the reforms that creditors demanded in exchange for keeping Greece financially afloat since 2010.
