Overview
- The UK, Sweden, France, Germany and the Netherlands say toxicology on preserved samples conclusively detected epibatidine, a potent neurotoxin associated with South American poison‑dart frogs.
- The governments assert the toxin does not occur naturally in Russia and say it likely caused Navalny’s 2024 death while he was held in an Arctic penal colony.
- They attribute responsibility to the Russian state, arguing it alone had the means, motive and opportunity to administer the poison in custody.
- The five countries have formally notified the Organisation for the Prohibition of Chemical Weapons, framing the case as a breach of the Chemical Weapons Convention.
- The Kremlin dismisses the claims as partial and unfounded, with officials deriding the reports as propaganda, as Navalny’s widow welcomes the findings at the Munich Security Conference and recalls his earlier Novichok poisoning in 2020.
