The inclusion is a EU project. It’s very unlikely that he can legally segregate schools.
I’m not particularly happy about the inclusion project myself, because it has currently only lead to mindless cost cutting and worse teacher to pupil ratio, but I’m hopeful that it’ll have positive impact once the implementation is properly finished. All EU countries are struggling to figure it out and they will eventually.
It’s still delusional that this guy thinks he will have the power to change it. Don’t vote for idiots like that. Anyone can make empty promises.
