Austrian election results: Sebastian Kurz becomes Europe's youngest leader

Sebastian Kurz is certain to become the world’s youngest leader at just 31 after his conservative People’s Party (ÖVP) becomes the clear winner in Australian polls.

“Today we have won a huge mandate to change this country, and I promise you I will work with all my energy for change,” Mr Kurz told cheering supporters.

“We want to establish a new culture in politics. And we want to change the country for the better.”

Mr Kurz now has a mandate to pursue the hard-line anti-immigrant policies he introduced as the party leader.
