Former prime minister Antonis Samaras spoke on the phone Monday evening with his one-time coalition partner and the head of Greece’s newest political formation to enter parliament, the centrist Potami party — shortly after a Eurogroup meeting ended on a sour note vis-à-vis the Greek bailout crisis.

Samaras contacted both socialist PASOK leader Evangelos Venizelos and Potami’s Stavros Theodorakis in what sources close to the ex-premier termed “coordination of the pro-European political forces”.

The same sources said contacts will continue over the coming days.

An anticipated meeting this week by the central committee of Samaras’ conservative New Democracy party has also been postponed, given the fluid political situation emanating from the impasse between the radical leftist Greek government and its eurozone creditors.
