Hungary has ordered 10 Russian diplomats to leave the country, accusing them of conducting activities deemed “unacceptable” and incompatible with their diplomatic status. The announcement, made by Hungary’s Deputy Prime Minister and Foreign Minister Anita Orban on Tuesday, was framed as a measure to protect the nation’s security and sovereignty.

This decision marks a significant shift in Hungary's approach to its relations with Russia, particularly in the context of the ongoing conflict in Ukraine. While many European Union member states expelled Russian diplomats following Moscow's full-scale invasion of Ukraine in 2022, Hungary had not previously taken such action. The move comes after a period of historically warm relations between Budapest and Moscow under the previous government.

Anita Orban stated that the expulsion does not signify a complete breakdown of diplomatic ties with Russia. However, Russia has vowed retaliation. Maria Zakharova, Russia’s Foreign Ministry spokeswoman, told the TASS news agency that Moscow would deliver a “harsh and painful” response to Hungary’s decision.

The European Union has acknowledged Hungary’s action, with EU spokesman Christian Wigand calling it a “legitimate decision.” He added that the EU would continue to “closely coordinate” on the matter, indicating a unified stance among member states regarding security challenges posed by Russian diplomatic activities.

Under the leadership of former Prime Minister Viktor Orban, who lost power in April after 16 years, Hungary maintained a notably closer relationship with Russia compared to most other EU nations. Reports indicated that Orban had expressed a cooperative stance towards Russian President Vladimir Putin.

The political landscape in Hungary has recently changed, with Peter Magyar’s Tisza party securing a substantial parliamentary majority in the elections held last month. This new government is now navigating Hungary's foreign policy and its relationship with Russia.

The expulsion of diplomats is a serious diplomatic measure, often employed when a country believes foreign representatives are engaged in espionage or other activities detrimental to national security. The specific nature of the “unacceptable activities” was not detailed by Hungary’s foreign minister.

As Hungary joins other EU nations in expelling Russian diplomats, the diplomatic fallout between Budapest and Moscow is expected to intensify. Russia's promised retaliatory measures could potentially affect Hungarian interests or diplomatic presence in Russia, leading to further escalation of tensions.
