"Syriza is not calling to quit the euro zone or the European Union. Syriza has put forth a plan on how to restore and reorganize the country, cancel the Memorandum [of Economic and Financial Policies] and the austerity policy, take leave of the troika of lenders and follow through on the program to fight poverty that has resulted from the Memorandum, and, of course, to write off a bigger chunk of [national] debt. These are our priorities and we are going to deliver on our agenda," Panayiotis Lafazanis said.
Greece will vote in snap parliamentary elections on January 25. The vote was called by Prime Minister Antonis Samaras after his candidate for president was rejected three times by parliament.
Speaking on Greece's cooperation with the NATO military bloc, Lafazanis said the party was aiming at "freeing the country from neo-colonial shackles."
The anti-bailout Syriza party, or Coalition of the Radical Left, won a resounding victory over Samaras's conservative New Democracy party in the European Parliament elections in May 2014, grabbing more than 26 percent of votes and sending six lawmakers to the European Parliament.
Greece's Coalition of the Radical Left, Syriza, will put an end to the state program of privatizing ports and railroads, should it win the upcoming election, Lafazanis said.
Russian Railways is among those companies bidding on the privatization of a railroad network and a port in the Greek city of Thessaloniki.
"We will reorganize Greece's railroads in a new enterprise, therefore stopping their transformation, and they will remain a state-run company," Lafazanis said.
The politician also expressed certainty that Syriza would gain the majority in the upcoming January 25 parliamentary election.
The left-wing and adamantly eurosceptic Syriza is Greece's second-largest political party. The latest pre-election polls showed popularity for Syriza to be above incumbent Prime Minister Antonis Samaras' center-right New Democracy party by over 3 percentage points.
