That could well signal it's already curtains for Syriza with less than three weeks to go to new elections.
From the story here at the Greek Reporter:
"On Monday, his speech writer Theodoros Kollias resigned stating that SYRIZA has lost its founding ideals. On Tuesday, the SYRIZA Youth issued a statement saying they withdraw their support to the party in the upcoming elections. Also, the same day, another part of the SYRIZA coalition, the Communist Drift, left the party and will join new SYRIZA offshoot Popular Unity. ...
"In social networks the party and its leader are ridiculed for the 180-degree turn from militant leftists to a more conservative, pro-euro political entity. The 20-24 percent the party gets in opinion polls is nothing compared to the 45-plus percentages they were getting just three months ago."
