In an opinion poll published in the Sunday newspaper To Vima, 66 percent opposed the new austerity measures, but 52 percent said the government, which emerged from June elections, should be given more time to handle the economic crisis.
The poll showed Syriza, which placed second in the June elections, ahead of the coalition leader, the center-right New Democracy party, by nearly 3 percentage points. The extreme right-wing nationalist Golden Dawn party continued its strong showing with more than 10 percent of respondents preferring it.
The poll, which involved 1,017 respondents, had a margin of error of 3.07 percentage points.
