Nope, a lot of the right-wing parties got large boosts. It's basically a tendency throughout Europe, as we see the eastern workforces come in and knock down wages by quite a bit.
Funny thing is, they're usually very EU-skeptic as well, and often very socialist thinking (what we'd call social democrats, ie slightly left of the center in the political spectrum- aka, the European spectrum). But some of their nationalistic views place them as extreme right-wing, but their social politics have caused them to basically vanquish all the old anti-EU parties, who were generally considered left-wing, resulting in the right-wing parties taking the left-wing votes. Very extreme voter-switches tbh.
