| Alexander Van der Bellen (L) beat Norbert Hofer (R) by only 30,863 votes in the May vote |
A re-run of Austria's presidential
election looks set to be postponed on technical grounds - because the
glue will not stick on postal vote forms.
He narrowly lost to Mr Van der Bellen, the former Green Party leader.
Mr Van der Bellen told a news conference on Saturday that he was braced for a postponement. "I hope that [the election] can still take place this year," he said.
A number of postal voters have complained in recent days that the glue on their ballot forms was not working properly, making the seals insecure, Die Presse reports.
Mr Sobotka said on Friday that it was unlikely the problems could be resolved in time for the 2 October date, and said he would make a further announcement on Monday, fuelling speculation he will announce a postponement.
Die Presse cites government officials as saying a number of different dates, from November to January, are being considered.
