The far-right label really only makes sense when divided into far-right (German/Austrian nationalist), far-right (Italian nationalist) and far-right (Padanist).
That's a very outdated view.
Fact is that today's far-right in Austria and Italy (Strache and Salvini) work closely together and are best buddies.
I'm surprised that they have not campaigned together at a joint event in Bozen/Bolzano yet. Probably because they each want to shore up their own party base. I guess, personally they would.
Yes, I know that in the last European Parliament elections Die Freiheitlichen ran on the Lega Nord list. That's why I didn't lump the Lega together with the Italian nationalist parties. And it's true that the immigration issue among others has provided common ground for Italian and anti-Italian nationalists alike. Additionally some Italian New Rightists have sympathies for self-determination etc. for ideological reasons. But still parties like Fratelli d'Italia and Die Freiheitlichen are very much antipodes.
