"syriza, which was the absolute extreme left any party across the EU could be" That's a bit hyperbolic; it's not even the most left-wing party in the Parliament of the Hellenes -- that title should go to KKE, the Communist Party of Greece, which has 15 deputies. There are minor parties even to the left of them (e.g. ΑΝΤ.ΑΡ.ΣΥ.Α, the Anticapitalist Left Cooperation for the Overthrow and Front of the anticapitalist, revolutionary, communist left and radical ecology), which holds 1-1.5% of the regional governmental seats across Greece. SYRIZA sits with the same European Parliament grouping as Die Linke, which is the fourth largest party in Germany, holding 10% of the seats in the Bundestag. It's difficult to say that SYRIZA is tremendously more left wing than Die Linke is. They're certainly less left-wing than Enhedslisten, the Danish Red-Green Alliance, which propped up a social democrat government in the Danish parliament from 2011-2015. There are plenty of Marxist-Leninist and Trotskyist parties in various national parliaments, and more in regional parliaments. An example is the Partido Communisto Português, which has about 6% of the seats in the Assembly of the Republic and a bit more than 10% of the seats in local governments across Portugal. There's even a few elected positions held the Maoist Workers' Party of Belgium. SYRIZA is not THAT far to the left!
