ATHENS: Greece's anti-bailout Syriza party has widened its lead over the ruling conservatives, two surveys showed on Thursday, days before a snap national election.

A poll by Metron Analysis to be published on Friday showed Syriza would win 36 percent of the vote, ahead of Prime Minister Antonis Samaras' New Democracy party which would take 30.7 percent of the vote.

The 5.3 point gap is up from 4.6 points in a previous survey.

A second poll by Rass showed the gap between the parties at 4.8 points from 4.2 points in a survey published on Wednesday.
