the preliminary results for the PR vote in Italy (with my ignorant (but still better than John Oliver's?) attempts to summarizing each party):
Five Star - 32% (sorta no platform, anti-europe, anti-coalition party started by that comedian though he's somewhat not part of it anymore)
Democratic - 19% (basically standard social democrats, main party of left coalition, was governing party)
Lega Nord - 18% (former secession movement that's turned into either a populist anti-europe anti-immigrant party and/or an outright fascist party depending on the day of the week, now the largest party in right coalition)
Forza - 14% (Berlusconi's reboot party, previous largest party in right coalition and like "vote for the crook, it's important" type status)
Brothers of Italy - 4% (part of right coalition, anti-Europe conservatives but with legacy tied to past fascist parties, also founded by and run by a woman...so MISLEADING NAME)
Free and Equal - 3% (non-coalition left party/alliance, like a wee step to the left of social democrats)
More Europe - 3% (part of left coalition, the current state of the historical Radicals, classical liberals/left-libertarian alliance, pro-Europe)
Us with Italy - 1% (part of right coalition, more standard european christian democrat party)*
Together / Pop Civic List / some regional parties - combined 1.5% (part of left coalition, mishmash of progressive, green, and christian democrats)*
none of the parties or coalitions are going to get 40+% to form a government...this is the worst the Democratic Party has ever done since its founding...the five star, lega, and brothers combo of 54% of the vote means that basically the only solution of a Berlusconi + left coalition agreement that people were hoping on won't really get anywhere even if they pull in free and equal, they'd be able to form a government, but couldn't do anything
*may not get over threshold for PR seats depending on where the votes come from
