Geert Wilders, leader of the Dutch Party for Freedom, congratulated Dutch Prime Minister Mark Rutte on his victory in Wednesday's parliamentary election.
Wilders said he did not understand Rutte's comment that Dutch voters had said no to the "wrong kind of populists".
"I don't know what he means. He is implying there are good and bad populists. I don't see myself as a populist but he is suggesting I am a bad populist and some kind of Nazi," he said, according to Reuters.
