Purely political manoeuvring by wilders. An attempt to avoid the constitution failed. Since then the minister for immigration, of his party, has come up with nothing. Absolutely nothing except refusing to sign off on a royal reward for immigration volunteers.
The present government is rightwing, a coalition of 4 parties. 2 of those parties have lost a lot of support since this administration started, so he's banking on new elections and gaining ground. Elections probably in October or so, so still lots of time for things to change, but atm i think the sentiment is moving more to the center.
