Voters were given a taste yesterday of what to expect over the coming days as New Democracy and PASOK turned their fire on each other ahead of the October 4 general election. «PASOK has no policy program; they are not trustworthy; all they have is propaganda,» said ND campaign spokesman Giorgos Koumoutsakos. «They do not know how to get the country out of the dire straits caused by the global economic crisis.» PASOK spokesman Giorgos Papaconstantinou responded in kind. «The only threat to our country is the lack of action and the wrong policies of this government,» he said. Both Prime Minister Costas Karamanlis and PASOK leader George Papandreou are expected to repeat similar messages on the campaign trail. Karamanlis spoke in Kozani yesterday and is due to appear at a rally in Patra today before going to Iraklio, Crete, tomorrow. Papandreou spoke in Iraklio last night, will be in Larissa today and will make an appearance in Thessaloniki on Tuesday. The Athens prosecutor’s office yesterday launched an investigation into the illegal publication of some new opinion polls on several blogs. Current electoral law forbids the publishing of survey results in the last two weeks of the campaign. Meanwhile, two groups of hooded assailants attacked the new and former PASOK headquarters in central Athens yesterday evening. The attackers threw Molotov cocktails and rocks at the buildings before dispersing into side streets in Exarchia. Nobody was injured and no arrests were made.
