There has been a serious electoral development, the main center-left party SYRIZA is in internal crisis after the purge of it's most popular and vocal MP over his allegations that the greek judiciary is corrupt.
An own goal by Tsipras really, corruption in the greek judiciary is so widely perceived that has even been used internationally to refuse legal extraditions to Greece in some occasions.
By purging the MP who made those allegations he invites critisism that he himself is corrupt, just before an election.
However there is also the perception that he had no choice, after the government passed an amendment to the electoral law allowing it to ban political parties, opposition parties are now on their toes not to give a pretext to be banned.
That seems uh. A bit concerning. Is Mitsotakis trying to go full Orban?
Of course not. ND is a mainstream centre-right party, and Mitsoakis is on its liberal wing to boot: he supports EU membership for Macedonia and Albania, sent arms to Ukraine, passed a conversion therapy ban and so on. That's not to say Mitsoakis hasn't done some dodgy stuff on things like migration, but I think our Greek friend is getting a bit ahead of himself.
The actual law is this:
Greece bans parties with convicted leaders from running in electionsUnder the amendment, parties cannot run in elections if their "real leaders", not only their official representatives, have been convicted at any instance for crimes that carry a sentence of up to life imprisonment, ranging from treason or spying to participating in a criminal organisation.
Golden Dawn was notorious for being a literal criminal organization: their leader and 6 MPs are currently in prison for murder. I presume the same is true of their now banned splinter and it's cases like this the law was tailored to.
