All ministers from Austria's far-right Freedom Party (FPÖ) have resigned, throwing the government into chaos.
The Freedom Party's leader Heinz-Christian Strache, who was also vice-chancellor, was forced to resign at the weekend after a video sting.
The scandal broke on Friday when footage from 2017 was published in German media, showing Mr Strache and another party official proposing to offer government contracts to a supposed Russian oligarch's niece.
The party threatened a mass resignation earlier on Monday if Interior Minister Herbert Kickl was also forced out.
Chancellor Sebastian Kurz had called over the weekend for Mr Kickl to be sacked, saying that as general secretary of the party he should take responsibility for the scandal.
