Greece has very little history of Left Wing Governments; can't recall one at least since the colonels.
After the war, Greece fought a civil war over the complexion of governments there - the West backed the right.
My father's brother was a decorated war hero in WW2, yet he was court martialed for refusing to go to Greece to train the Fascist "security battalions" which came into being in support of the Nazis, but later played a key part in the Civil War.
The right and centre have always made the running there, before and after the colonels
