None of the parties, running in Greece's crucial second general elections, will command a majority, private polls, cited by foreign media, show.
The centre-right New Democracy party had a three-point lead over the radical left Syriza coalition, but neither party would capture even 30 per cent of the vote, according to two private polls seen by the FT.
Syriza is considered to be likely to overtake the conservatives and take a 50-seat bonus awarded under Greek electoral law to the front-running party, according to the poll.
"Pro-European" New Democracy party has taken a lead with 29% of the vote, closely followed by the anti-bailout far-left Syriza party with 27%, a socialist Pasok party official told the Guardian.
Pasok is in third with 12%.
Exit polls will be released at 7pm Greek time, but they may not be clear enough as the number of undecided voters stands at 15%.
