We had 2 state elections in Germany last Sunday, in both the AFD lost heavily.
Polls for general election show a ~2% loss for September (they had 12.6% in 2017, looks like 10-11% now).
Netherlands elections are only a slight uptick from 2017 it seems, mostly (according to polls) during the earlier years of the last 4 year period. (I don't really follow that though)
I have the feeling that support kinda reached its max and especially Brexit is actually hurting far right parties now. We will see how it will go.
For that policy, I don't really have a negative opinion on it. I am a huge proponent of immigration if people integrate. Sadly huge communities of only immigrants are contrary to that. So splitting them up somewhat kinda is the easiest solution. As I understood, the new policy does not make immigration harder, does it? (maybe I just misread though)
I don't know how often these communities exist, especially in other countries, but here pretty much all immigrants I know try to integrate. Then again I guess that they seclude themselves from the rest is exactly why I may never meet them.
A former colleague of mine came from China nearly a decade ago. He worked 2 years for us and in the end was let go because even after all that time it was hard to talk in German or English. And sadly he often had problems to follow in meetings and it was hard to discuss solutions. We all liked him, so we were really sad it came to this. But his problem was that after work he went into his circle of Chinese friends (and wife) and never spoke German/English other than the few bits at work every now and then.
