Austrian legal officials say the country's right-wing party is challenging the results of elections for the presidency that was narrowly lost by its candidate.

Constitutional Court spokesman Christian Neuwirth said Wednesday that the Freedom Party is claiming numerous irregularities in the May 22 election, particularly for the absentee vote count.

Freedom Party candidate Norbert Hoffer was leading after polls closed. But final results after a count of absentee ballots put former Green party politician Alexander Van der Bellen ahead with only a little more than 30,000 votes.
