Home affairs minister Piet Hein Donner said on Thursday he wants political parties declare the names of any donors giving more than €4,500 to their party.

This will have particular consequences for the anti-Islam PVV, says the Telegraaf.
Geert Wilders’ party receives a lot of gifts from outside the country, particularly from the US. At the moment, these are given to a foundation, the friends of the PVV. Donner, however, wants a change in the law so these kind of foundations have to declare donations, says the paper.
Wilders has always refused to name his donors.
The Christian Democrats will also be hit if the law is changed. They, too, often use a foundation construction for their donations.
