# Hungary quietly expels Russian diplomat alleged to be SVR officer
Hungary quietly expelled a Russian diplomat in Budapest who was alleged to have spent years cultivating contacts in think tanks and academic institutions close to the Orbán government, according to VSquare. The reporting says the diplomat, Artur Sushkov, left the country on May 4, 2026, along with his spouse, after Hungarian authorities identified him as an undercover officer of Russia’s Foreign Intelligence Service.
The case is significant because it combines counterintelligence, political timing and elite-access networks in one of Europe’s more Russia-friendly environments. VSquare said Hungary’s own counterintelligence service wanted to remove Sushkov earlier, but the Orbán government blocked an initial proposal in February 2026. The report framed that delay as political calculation tied to relations with Moscow and the run-up to the electoral defeat of Viktor Orbán.
According to the piece, Sushkov held the post of third secretary at the Russian Embassy and had previously served in Hungary from 2019 to 2022 before returning in 2023. The report said he used the diplomatic cover to build a network around pro-government think tanks and foreign-policy institutions, including the Mathias Corvinus Collegium, the Hungarian Institute of International Affairs and the John Lukacs Institute at Ludovika University.
Those institutions matter because they sit close to Hungary’s political and security establishment. VSquare said Sushkov’s activities included searching for informants and potential recruits, and arranging off-the-record meetings with people who had ties to government decision-makers. The report also said the operation was carried out by Hungary’s Constitution Protection Office together with the security service of an unidentified NATO country.
The reporting goes beyond one diplomat to sketch a broader pattern of influence and counterintelligence friction under the Orbán government. It says the government had long resisted or delayed the removal of Russian intelligence operatives operating under diplomatic cover, and quotes a former counterintelligence officer arguing that weak political consequences make a country attractive to hostile intelligence services. That is commentary, but it underlines the larger concern.
VSquare also said Sushkov’s spouse was quietly expelled and that the couple had multiple official addresses in Russia, including in Moscow and Kaliningrad. The report used those details to support the allegation that the embassy post was linked to intelligence work rather than routine diplomacy. It also said leaked flight data showed trips between Budapest and Russia and later between Budapest and Kaliningrad.
What cannot be independently verified from the excerpt alone is the full internal process by which Hungarian authorities identified Sushkov or exactly what evidence triggered the expulsion. But the reported result is clear: a Russian diplomat was removed, the case was kept quiet, and it was tied to a counterintelligence effort that apparently ran through both Hungarian and NATO channels.
The episode highlights how intelligence work in Europe often unfolds in institutional gray zones, where diplomacy, academia and politics overlap. In this case, that overlap appears to have been enough to keep a suspected Russian operative in place until the political environment changed.
