An opinion poll published by Efimerida ton Syntakton on Saturday gave SYRIZA a 2.5 percentage point lead over New Democracy.
The poll by Pulse put the opposition party on 22.5 percent and the conservatives on 20 percent. Golden Dawn remained third with 11.5 percent and was followed by PASOK and the Communist Party on 5.5 percent each.
Independent Greeks came next with 4.5 percent, while Democratic Left is right on the threshold for entering Parliament with 3 percent.
Significantly, a clear majority of Greeks believe that SYRIZA would win in the event of general elections being called early, according to the Pulse survey. Just under half of respondents (47 percent) think the leftists would be victorious, compared to 33 percent who believe New Democracy would come out on top.
