Austrians have gone to the polls in a presidential election that serves as a bellwether for rising populist sentiments in Europe.
Norbert Hofer of the right-wing populist Freedom Party enters the run-off election as the favourite, after the 45-year-old won the first round in April with 35 per cent of the votes.
Alexander Van der Bellen, a 72-year-old former Green party leader, came in second in April, with 21 per cent. Although he runs as an independent, his campaign was financed by the Greens.
As the Freedom Party has a eurosceptic and anti-immigration stance that is also followed by other populist parties in Europe, the presidential race has drawn an unusual amount of attention abroad, especially in neighbouring Germany, where the right-wing Alternative for Germany (AfD) enjoys growing support.
Andre Poggenburg, the AfD chief in the eastern German state of Saxony-Anhalt, said that a win by Hofer would be a signal for Germany and noted an "atmosphere of change when it comes to national parties" in Europe.
