Yeah, Eurosceptic parties had a mixed bag this year. In the Netherlands, Geert Wilders might get the worst result in his history with only 4%, and the other Eurosceptic party also only reached 11%, way below it's expectations. In Belgium however, the Vlaams Belang seems to have an historic good result, with the N-VA being the other big winner.
N-VA is still the biggest party but they're not a 'big winner', they actually lost a few % compared to 2014. Vlaams Belang did indeed reach a historic high, after reaching their low point in 2014. I suppose this is mostly due to voters switching from VB to NVA back then, and switching back now.
The victory of VB will be most notable in the parliament here, since all other parties seem to be completely unwilling to let them in the government.
On European level, this puts eurosceptism at a record high for Belgium, but VB still won't get higher than 15% (so it's still only about the same result as in the Netherlands).
Wallonia is pretty remarkable, it seems to be one of the few places in Europe where the far right isn't able to get big.
