On the 30 May, taking advantage of the popularity, the Vengaboys themselves went to Vienna to do an improvised street concert at Ballhausplatz singing the tune. Russian Turkmen-born businessman Igor Makarov, who the woman on the Ibiza video claimed was her uncle, made a statement published by the Russian edition of "Forbes" on 18 May 2019. He said he had no relation or connection to the woman on the video, and added that he was an only child. Makarov is now "using all lawful means to establish who was behind the illegal use of [his] name." Tajana Gudenus, Johann Gudenus′s wife who comes from a Serbian family that left Croatia for Banja Luka in 1992, made a statement through her lawyers on 22 May 2019. She stated she was not responsible for the collapse of the Austrian government, nor did she in any way influence the events that led to the resignation of Heinz-Christian Strache. On 25 May 2019, Russian media reported that Russian actress and TV presenter Lera Kudryavtseva intended to file a suit against the Austrian daily "Österreich" for mentioning her name and using her photo in the newspaper′s publication that suggested she might have been the Russian woman in the Ibiza video. On 17 May 2019, Chairwoman of the Social Democratic Party (SPÖ) and leader of the opposition Pamela Rendi-Wagner called for the immediate resignation of Strache and Gudenus. The next day, she asked for Chancellor Kurz to advise President Alexander Van der Bellen to dismiss Strache. Later that day, she summoned a special meeting of the National Council and asked for Strache and Gudenus to be held accountable there. At a press conference, Rendi-Wagner reaffirmed her condemnation of the intents and plans of Strache and Gudenus showcased in the video. She also stated that the simple resignation of both politicians would not suffice, it would need "complete clarification" of the case and new elections. A few hours after the video tapes were published, Werner Kogler, leader of The Greens and the party's frontrunner to the European elections 2019, said the affair was "a case for the prosecutor". On 18 May 2019, one day after the videos' release, he joined thousands of protesters on Ballhausplatz, demanding new elections. Following Strache's resignation, Kogler further called for the dismissal of the Interior Minister, Herbert Kickl.
