VIENNA (AP) -- Austrian Foreign Minister Alexander Schallenberg will serve as the country's interim leader while the far-right Freedom Party attempts to put together a new coalition government, the president's office said Wednesday.

Schallenberg, 55, will take on the duties of outgoing Chancellor Karl Nehammer, who announced his resignation over the weekend after his efforts to put together a coalition without the Freedom Party collapsed. Nehammer plans to step down on Friday.

President Alexander Van der Bellen's office said in a statement that the head of state will formally task Schallenberg with "continuing the management of the chancellery and leading the interim government."

It will be Schallenberg's second -- and, again, likely brief -- stint as Austria's leader. Schallenberg served as chancellor for less than two months in late 2021 after Sebastian Kurz resigned, before passing the job to Nehammer and returning to the Foreign Ministry.

The anti-immigration, euroskeptic and Russia-friendly Freedom Party won Austria's parliamentary election in September, but was initially shunned by other parties.

After Nehammer announced his resignation, his conservative Austrian People's Party made an abrupt U-turn on its previous refusal to contemplate working with the Freedom Party under its leader, Herbert Kickl.

On Monday, Kickl received a mandate to try to form what would be the first national government led by the far right since World War II. That's a process that could take weeks or months, and isn't guaranteed to succeed.

Schallenberg has said he wouldn't stay in the government under Kickl.
