Is there anywhere that epitomizes the Judean People's Front as much as the Greek left?
Hell Greece is a country where the Marxist-Leninist Communist Party of Greece and Communist Party of Greece (Marxist-Leninist) can't get along and need to be two seperate parties.
It always depends on what you mean by
left. Everything to the left of mainstream social democrats/socialists and mainstream greens? Or only self-declared communists?
The Greek left seems to be quite far from People's Front of Judea mode. One very strong radical left party and one relevant orthodox communist party.
When it comes to sectarian communist splinters you also find similar situations in Germany (DKP, MLPD, PSG, KPD[1990], ABfdWdKPD, etc.), Britain, France etc.
Italy's communists are now in complete PFJ mode:
Communist Refoundation Party [PRC] (once a relevant party at 5-10%, now 1-2%)
Party of the Italian Communists [PdCI] (ideologically more orthodox, but at the same time more moderate PRC splinter, once 2-3%)
Communist Party of the Workers (trotskyist PRC splinter)
Critical Left (trotskyist PRC splinter)
Communists Popular Left - Communist Party (PdCI splinter)
Marxist-Leninist Party of Italy
Resistance Support Comittees for Communism
