Social Democrat leader Andreas Babler told public broadcaster ORF that he wanted it to be a central condition for potential coalition negotiations, after Austria's next general election which is due later this year.

Its general secretary, Christian Stocker, said that while Mr Babler wanted to "to further burden people in our country with his call for a wealth and inheritance tax, the People's Party is providing relief. We reject new taxes; people must be left with more net income."

"Nothing can justify...what happened here," Babler said in a statement.

The party's electoral commission head Michaela Grubesa said on Monday the results had been attributed to the wrong candidates and the winner was in fact Andreas Babler.

The correct count was 280 votes for Doskozil and 317 votes for Babler, or about 47% to 53%.
