Hungarian opposition politician and lawyer Péter Magyar gathered with thousands of demonstrators Friday before the nation’s Interior Ministry to demand the resignation of the head of the institution, Sándor Pintér.

Magyar, the former husband of the resigned Minister of Justice Judit Varga, called for the protest on Facebook earlier that day and demanded Pintér claim responsibility over a recent government scandal. In February the president and the minister of justice pardoned an orphanage director who was convicted for covering up a sex abuse case in the institution he managed, and the two officials then resigned.

The scandal caused other protests earlier this month, which were also led by Magyar. The new opposition leader has seized a chance to prominence in the Hungarian opposition scene after secretly recording a conversation with his ex-wife and implicating a top minister in a corruption case.

Magyar, who has been publicly voicing the scandal, used the case to call into question Prime Minister Victor Orban’s platform of upholding Christian politics, and Orban himself considered the scandal to be a “nightmare.” Moreover, the scandal has affected the current government’s credibility on its policies against the “LGBTQ frenzy.”

Magyar is the current vice president of TISZA, a new political party in Hungary that will be running in the upcoming European elections on June 9. In a recent post, Magyar stated that anyone who believes the current government is the government of Hungarian families and protects Hungarian children should vote for Orban’s party Fidesz, which is currently in power. If not, he added, the TISZA party is there for everything else.

According to recent research by the Compass Institute, which was also shared by Magyar, TISZA is the strongest opposition party in Hungary.
