Samaras spoke at a party event on the occasion of Greece's accession to the European Economic Community (today's EU) in 1980.
Referring to this week's rapid-fire developments, he cited the high-profile proposals for a referendum, rumour-mongering of "no money after July" and even the Greek EU Commissioner's warning that some quarters are planning Greece's exit from the eurozone, "claims which are continuously denied", as he said.
"On our part, we, New Democracy, confirm that we completely agree with the targets concerning fiscal restructuring. We cannot, however, support the ways with which they were decided. We agree with the target; we do not support, however, the means."
Moreover, he reiterated his call for a renegotiating of the memorandum.
