Boris Nadezhdin, one of the few remaining public critics of the war in Ukraine inside Russia, announced on Sunday that he was ending his campaign for September’s State Duma elections. He stated that a series of recent legal measures—including his designation as a “foreign agent” by the Justice Ministry and a court fine for displaying “extremist symbols”—had exhausted his ability to legally participate in opposition politics. His team would not submit the collected signatures, and he expressed unwillingness to put his supporters and family at risk.

The immediate triggers were procedural. Nadezhdin was added to the foreign agent registry on 10 July, a status that under Russian electoral law bars candidates from holding public office. Days later, a Moscow region court fined him 1,000 roubles for sharing a video in 2023 that briefly showed a photograph of the late opposition activist Alexei Navalny, whose organisations were previously banned as “extremist.” The politician also received a travel ban, which he attributed to the reopening of an old enforcement proceeding linked to his earlier bankruptcy case. In a Telegram post, Nadezhdin said these actions “silenced” him and were intended to force him out of politics.

Nadezhdin, a former adviser to senior Kremlin figures including current deputy chief of staff Sergei Kiriyenko, gained prominence during a 2024 presidential bid in which he openly called for an end to the conflict in Ukraine. Although his candidacy was rejected due to alleged signature irregularities, long queues of supporters across Russia turned the signature drive into a visible anti-war protest. His withdrawal now leaves the Duma race without a prominent advocate for peace. Political analysts in Moscow note that pressure intensified as the Kremlin faces domestic discontent over the war, drone attacks on Russian cities, and slipping approval ratings for President Vladimir Putin. In a BBC interview, Nadezhdin himself suggested he had long been protected by one faction inside the presidential administration, but that the recent moves reflect the ascendancy of siloviki—security-service hardliners—who seek to block any electoral presence critical of the military operation.

Since Russia’s full-scale invasion of Ukraine in February 2022, authorities have intensified a crackdown on opposition voices, with the “foreign agent” and “extremist” labels increasingly used to marginalise critics. Hundreds of opponents are now jailed, in exile, or dead. The legal tools deployed against Nadezhdin exemplify the narrowing space for even established politicians who question the war. Looking ahead, Duma elections are scheduled for September 2025; with Nadezhdin out, the ballot is expected to feature no candidates openly advocating a negotiated end to the fighting. The politician said he hopes his exclusion is temporary, but for now his ability to operate legally is, in his words, “exhausted.”
