Local agency ANP, which tallies and publishes the ballots, earlier Friday had said Wilders and his PVV Freedom Party could not catch the D66 with only a handful of votes still to count.
Wilders posted on X a screen grab of a message claiming without evidence that more than 100 votes had not been counted in the city of Maastricht and suggested this could have happened elsewhere.
Another screen grab showed a message claiming, also without evidence, that 15 ballots boxes of votes had disappeared in Zaanstad, near Amsterdam.
“It’s raining messages like this from all around the country,” said Wilders.
“I don’t know if it is true or not, but it would be good for it to be investigated.”
