VIENNA — Austrian far-right leader Herbert Kickl said Wednesday that his talks on forming a coalition government with a conservative party have collapsed.

Austria’s president gave Kickl a mandate to try to form a new government on Jan. 6 after efforts to put together a governing alliance without his Freedom Party failed.

But his talks with the conservative Austrian People’s Party appeared increasingly troubled in recent days, with constant talk of policy differences and a clash over who would get which ministries.

On Wednesday, Kickl informed President Alexander Van der Bellen that he was giving up the mandate to form what would have been the first national government headed by the far right since World War II.

Kickl’s anti-immigration and euroskeptic party, which opposes sanctions against Russia, won Austria’s parliamentary election in September. It took 28.8% of the vote and beat then Chancellor Karl Nehammer’s People’s Party into second place.

But in October, President Alexander Van der Bellen gave Nehammer the first chance to form a new government after Nehammer’s party said that it wouldn’t go into government with the Freedom Party under Kickl and others refused to work with the Freedom Party at all.

Those negotiations collapsed in the first few days of the new year and Nehammer resigned, making way for interim Chancellor Alexander Schallenberg.
