Voting began in Austria Sunday in a snap election tipped to see conservative Sebastian Kurz, 31, become the EU's youngest leader and form an alliance with the far-right, in the bloc's latest populist test.

His revamped People's Party is forecast to win more than 30 percent of the vote, leaving the anti-immigration Freedom Party to fight for second place with the Social Democrats. First estimates are expected shortly after polls close at 1500 GMT.
