Greece's right-wing New Democracy and left-wing Syriza parties are almost neck-and-neck after parliamentary elections, exit polls suggest, BBC reports.

New Democracy, which broadly supports a European bailout deal, looked to be almost tied with Syriza, which opposes the measure.

The outcome could decide Greece's future inside the euro.
The election was the second in six weeks, called after a 6 May vote proved inconclusive.

On that occasion, each of the main parties tried but failed to form a coalition government.

If the exit poll figures are confirmed in this result, Greece could be in for another period of instability.

The two main parties are each thought to have polled between 27 and 30%, the exit poll showed.

But though the result could be almost a dead heat, the party that does come out on top will receive an extra 50 seats in the 300-seat parliament.

The centre-left Pasok, a potential partner for New Democracy in a pro-bailout government, polled 10-12%, with several smaller anti-bailout parties on 5-6%.
