@kontrrewolucja Current or past? Currently the more radical groups are very weak and probably government infiltrated. Most don’t seem like a genuine option. More mainstream you got the two huge right wing parties in parliament. Party for Freedom and Forum for Democracy. The PfF (PVV in Dutch) is losing momentum, Forum is only gaining momentum and growing ever larger.
Forum is hardly a far right group, but they’re good nationalists and their leader has reactionary sympathies.
