Sellner, a prominent leader of Austria's ethno-nationalist Identitarian Movement, revealed the ban in a video on X, where he read out a letter purportedly from the authorities in the city of Potsdam.

The letter stated that Sellner was immediately barred from entering Germany for the next three years and warned of potential consequences, including deportation, if he attempted to enter the country. Moreover, if Sellner happened to be on German soil, he would have to depart within a month. While the spokesperson for the city authorities declined to disclose the identity of the EU citizen affected by the ban, Agence France-Presse confirmed that Sellner had received a "ban on their freedom of movement in Germany."

The mayor of Potsdam, Mike Schubert, emphasized the need to utilize legitimate means to demonstrate that the state is not powerless in the face of far-right extremism. Germany has witnessed substantial protests against extremism and the far-right Alternative für Deutschland (AfD) party, with some of its members present at the November meeting in Potsdam where Sellner gave a presentation. The event was attended by neo-Nazis, other extremists, and business supporters, and focused on the practicalities of carrying out mass deportations, referred to as "remigration" in far-right circles. The intended targets were migrants, asylum seekers, and German citizens of foreign origin deemed to have failed to integrate.

Sellner's recent deportation from Switzerland further added to his troubles. Swiss police, acting on their prevention mission, arrested Sellner and prevented a far-right gathering organized by the group Junge Tat, known for its far-right, anti-Islam, and anti-immigration ideologies, where Sellner was scheduled to speak.

It is worth noting that Sellner has come under international scrutiny due to his communication and receipt of donations from Christchurch terrorist Brenton Tarrant, who carried out mass shootings at mosques in 2019, resulting in the death of 51 people. Previously banned on Twitter in 2020, Sellner expressed gratitude to X's owner, Elon Musk, for restoring his account on the platform. As Sellner now boasts a verified account with over 51,000 followers, he expressed hope that others who have faced bans would also be reinstated.

Elon Musk himself responded to one of Sellner's posts, where he questioned the legality of the Swiss police's decision to shut down the far-right event and ban him from the region for two months. This exchange on X further highlights the ongoing debate surrounding extremist ideologies and the measures taken to counter their influence.

Sellner's ban from entering Germany serves as a strong message against the promotion of hate speech and extremist views. It demonstrates the German authorities' commitment to maintaining peace and security while countering the rise of far-right sentiments in the country.
