Austrian Vice Chancellor Heinz-Christian Strache resigned Saturday after being caught in a secret video footage offering government contracts to a potential Russian benefactor.

Strache, member of the populist right-wing Freedom Party of Austria, told the media in his announcement that he was illegally set up in a “political assassination," though admitted that his behavior was “stupid, irresponsible and a mistake.”

The resignation raises questions whether the current governing coalition consisting of Chancellor Sebastian Kurz’s center-right People’s Party and the Freedom Party of Austria will survive. Either Strache will be replaced with another party member or the coalition ends and new elections are called.

The daily Sueddeutsche Zeitung and the weekly Spiegel published on Friday excerpts of a secret video that showed Strache offering government contracts to a Russian woman, who claimed to be the niece of a prominent Russian businessman supposedly interested in investing in Austria.

The outlets refused to disclose the source of the footage but said it was authenticated by a forensic video expert.

The video reportedly lasts some six hours and was taken in a villa on the Spanish island of Ibiza. In addition to advising the woman to buy a newspaper, the politicians also appear to suggest ways of funneling money to his party via an unconnected foundation in a bid to circumvent Austrian rules on political donations.

Strache said during his resignation speech that he had no further contact with the woman and no contributions were made.
