Austria's presidential election is unlikely to take place on October 2 as planned due to a "glue crisis" caused by unsticking envelopes, Green-supported candidate Alexander Van der Bellen said on Saturday.
"I do not think that the date on October 2 is feasible," Van der Bellen told the press on Saturday.
His comments come days after the Interior Ministry confirmed that unreliable sticky strips on envelopes were rendering some postal votes invalid, once again damaging the credibility of the country's mishap-prone attempts to elect a head of state.
"Glue crises can occur anywhere. We will overcome this crisis," the presidential hopeful said.
Van der Bellen won the presidential election in May by a margin of 0.6 percentage points. His far-right opponent, Freedom Party candidate Norbert Hofer, cried foul and the country's Constitutional Court demanded a rerun after ruling that ballots and voting results had been handled improperly.
