The number of votes declared invalid increased by 78% in the second round of voting for the Austrian presidential election compared to the first round, prompting speculation of voter fraud.
Establishment candidate and Green Party leader Alexander van der Bellen won the vote by a razor thin majority of only 31,000 votes through postal votes after rival Freedom Party candidate lead by 144,000 votes.
Staatstreich blog says there is no explanation for the dramatic increase in invalid votes.
The voting cards had become simpler in the second round with only two candidates left to chose from as President.
Staatstreich argues that the number of invalid votes should only have been 98,400 if it had risen in proportion to the 6.2% more votes cast in the second round.
However, the number of votes declared invalid rose to 165,212, more than 67,000 more was to be expected on the basis of the first round of voting.
