It's too simple to say that "far right" or "fascist" parties did well in the European Parliament elections. It does seem clear that "Euroskeptic" parties on the right and left did well.

Anti-European Union and far-right parties posted strong gains in elections to the European Parliament in some countries on Sunday, tapping into voter anger over economic austerity and delivering a blow to institutions in Brussels, national governments and mainstream political parties.
