Both agreements are part and parcel of the 110-billion-euro bailout granted to Greece last year in order to stave off sovereign default, as well as a more-or-less prerequisite for any future bailout.
In comments published on Saturday in an Athens weekly, Samaras noted that "now is the hour that the entire course of our economic policy, which was implemented as of last year, should be re-evaluated. This policy was proved wrong in everything. Never before has an economic policy been so miscalculated."
He again underlined that three things are necessary: "an alternative plan; another government to implement it, and a smooth transition from the wrong initial plan to the alternative one».
Samaras insisted that if the current economic mix does not change then ND will not vote the new loan agreement, even if the ruling PASOK governments requests 180 votes in Parliament to pass the legislation.
Last week's mid-term programme was passed by a simple Parliament majority of 155 MPs out of the 300-deputy legislature.
Moreover, Samaras emphasised that various "injustices" recently enacted via tax hikes and pension cuts affecting the lower-income sections of Greek society will be overturned "as soon as a drastic cut in the (annual budget) deficit allows this ... If our policy is fully implemented then this will happen in three to four years"
Finally, he rejected the idea of a referendum in the autumn -- a proposal being floated by the government -- and reiterated that he wants snap elections.
His comments were carried in the weekly "RealNews".
