Two opinion polls published in the Greek press on Sunday saw ruling PASOK leading in the share of the vote but with a low overall percentage share that stood well below 30 percent. In both polls, the combined share of ruling PASOK and main opposition New Democracy was less than 50 percent.

An opinion poll conducted by the firm 'Pulse' and published by the "Eleftheros Typos" Sunday paper saw the ruling party's share of the vote decline to 23.5 percent, 3.5 points ahead of ND with just 20 percent.

The 'Pulse' poll placed the Communist Party of Greece (KKE) third at 9 percent, followed by the right-wing Popular Orthodox Rally with 5 percent and the left-wing Coalition of the Radical Left (SYRIZA) with 3 percent.

The remaining political forces now represented in Parliament, the Democratic Left led by Fotis Kouvelis and the 'Democratic Alliance' led by independent MP Dora Bakoyannis both 'tied' at 2 percent (lower than the ceiling for getting into Parliament), along with the Ecologists-Greens. A further 3 percent of voters expressed support for 'other' parties and 22 percent said they would either abstain or cast a blank vote, while 8 percent were undecided.

An opinion poll conducted by 'Rass' for the newspaper "Paron" gave PASOK a slightly higher percentage of 26.1 percent, compared with 22.7 percent for ND, giving the ruling party a 3.4 percent lead.

In this poll, 8 percent of voters said they would cast their vote for KKE, 5.1 percent of LAOS, 3.2 percent for SYRIZA, 3 percent for the Ecologists-Greens, 1.8 percent for the Democratic Alliance and 1.7 percent for the Democratic Left.

Another 2.8 percent declared a preference for 'other' parties, 2.6 percent said they would cast a blank or spoiled vote and 23 percent did not specify how they intend to vote.
