Austria is now western Europe’s only country with a far-right party sharing government power.

Incoming Chancellor Sebastian Kurz — who at age 31 will be the world’s youngest national leader — agreed Saturday to align with the controversial Freedom Party.

The Freedom Party, which was formed by an ex-Nazi SS officer after World War II, was last part of Austria’s government from 2000 to 2005.

Freedom Party leader Heinz-Christian Strache, 48, belonged to an alleged far-right paramilitary organization as a youth, the Sunday Times of London reported.

Kurz’s Austrian People’s Party will run the Finance, Economy and Justice ministries. Freedom Party politicians will run the Interior, Foreign Affairs and Defense ministries.
