> How easy will it be for the PVV to form a government with so few seats?
On a scale of 1 to 10? Belgium.
The problem isn't that he has only a ~quarter of the seats (last time a party had a similar lead was in 2012), it's that the results are too scattered. There are no realistic combinations.
PVV + VVD + NSC is the only possible combination with PVV, and I'm not seeing NSC go for that (for a number of reasons: ideological differences with PVV, history with VVD, probably not a good idea to participate in a coalition as a brand new party).
The other alternative is Labour/green + VVD + NSC + D66. It's similar to the purple coalitions of then 90s, but things changed quite a bit since then so I'm not sure how realistic that is, and it's probably going to end up disastrous for Labour (and D66) to be in a cabinet with a right-wing and centre-right party (as it has been in the past).
