Austrian President Alexander Van der Bellen on Wednesday swore in a new government led by Chancellor Sebastian Kurz after the former government collapsed in response to a controversial video.

Last week, two German news publications published a video showing former-Vice Chancellor Heinz-Christian Strache offering government contracts in exchange for media support from a woman posing as a Russian oligarch's niece.

Strache, who led the far-right Freedom Party (FPÖ), stepped down from his position as vice chancellor and as leader of the party, triggering the coalition government's collapse. Authorities are investigating revelations that emerged in the video.

'Full clarification'

Kurz will now lead the minority government. It includes Interior Minister Eckart Ratz, a former Supreme Court president; Defense Minister Johann Luif, army a deputy chief of staff; and Infrastructure Minister Valerie Hackl, who led Austria's air traffic control agency.

Foreign Minister Karin Kneissl, appointed by the FPÖ but not a party member, remained in her position.

Ratz is expected "to do everything to ensure full clarification, as far as the contents of the video rare concerned but also regarding the source of the video," Kurz said.

"With the swearing-in of an interim government, there is the possibility of conducting the affairs of state calmly and in an orderly way until election day," said Kurz.

No-confidence motion

But it is unclear whether Kurz's new government will survive even just one week. Parliament is scheduled to vote on a no-confidence motion put forward by the small leftist party Jetzt on Monday.

The motion could prove successful if the opposition center-left Social Democrats (SPÖ) and the FPÖ support it.

Senior SPÖ lawmaker Doris Bures said Kurz needed to take "confidence-building" measures if he wanted his government to survive.

"In life, you always have to earn trust," Bures said. "And the last few days have shown that the chancellor has done nothing to ensure that parliament, which at the end of the day will take this decision, can place this trust in him."
