Austria's president Monday swore in Sebastian Kurz as head of a new coalition government involving  Kurz's conservatives and the far-right, capping a year of successes for Europe's nationalists.

Kurz, 31, of the People's Party (OeVP) is chancellor and the world's youngest leader. Heinz-Christian Strache, head of the far-right Freedom Party (FPOe) is his deputy.
