Five European governments-the UK, Sweden, France, Germany and the Netherlands-have concluded that Alexei Navalny was killed with epibatidine, following government-backed analyses of biological samples taken from his body. The joint statement, issued on 14 February 2026 ahead of the second anniversary of his death on 16 February 2024, asserts that Russia had the means, motive and opportunity to administer the toxin while Navalny was imprisoned.

The announcement was made around the Munich Security Conference, where UK Foreign Secretary Yvette Cooper met Navalny’s widow, Yulia Navalnaya. The UK confirmed that its Permanent Representative had written to the Director‑General of the Organisation for the Prohibition of Chemical Weapons (OPCW) to notify an alleged breach. (gov.uk)
According to the governments’ statement, epibatidine is a lethal toxin naturally present in certain South American poison dart frogs and is not found in Russia. Officials said the confirmed presence of epibatidine in samples taken from Navalny admitted of no innocent explanation and pointed to state responsibility. (gov.uk)
Moscow rejects the attribution. Russia’s foreign ministry spokesperson Maria Zakharova dismissed the findings as a propaganda campaign and demanded disclosure of test results before offering further comment. (tass.com)
Under the Chemical Weapons Convention (CWC), using any toxic chemical as a weapon is prohibited, regardless of its origin or method of production. The Convention defines a “toxic chemical” as any chemical which, through its chemical action on life processes, can cause death, incapacitation or permanent harm. (cwc.gov)
The UK statement also links the case to the Biological and Toxin Weapons Convention (BWC), noting that toxins fall under its general‑purpose ban when used for hostile purposes. States Parties undertake never to develop, produce, stockpile or otherwise acquire or retain toxins except for peaceful purposes. (gov.uk)
Procedurally, the UK and partners have notified the OPCW. Next steps can include consultations and clarification under Article IX of the CWC and, where concerns persist, compliance measures recommended by the Conference of the States Parties under Article XII, up to referring matters to the UN Security Council. No request for an OPCW challenge inspection has been announced. (opcw.org)
Ministers signalled they would use all available policy levers. The UK has a standing chemical weapons sanctions regime allowing asset freezes, travel bans and related measures against those involved in prohibited chemical activities, alongside its Russia regime administered by OFSI. The EU maintains a horizontal regime targeting use and proliferation of chemical weapons. (gov.uk)
Epibatidine has been studied in toxicology and pharmacology for decades. First isolated from dendrobatid frogs, it acts on nicotinic acetylcholine receptors and was explored as an analgesic but abandoned due to extreme toxicity; reported potency for pain relief far exceeds morphine. Captive‑bred frogs do not produce the toxin, supporting the view that it is diet‑derived in the wild. (scielo.br)
The five governments place the epibatidine finding in a pattern of confirmed or alleged chemical attacks linked to Russia, including the use of a Novichok agent against Navalny in 2020 and the 2018 Salisbury attack. The joint statement describes repeated violations of the CWC and cites previous condemnations by European partners. (gov.uk)
For public bodies and corporates, the immediate practical steps are compliance‑driven: monitor for new UK or EU listings; ensure screening systems are current; and assess exposure to designated persons or entities. UK guidance sets out reporting duties and licensing routes where relevant. (gov.uk)
Navalny’s family welcomed the findings as long‑sought confirmation. European officials reiterated that, because the toxin is foreign to Russia and exceptionally rare, their assessments leave no credible benign route for its presence in Navalny’s body. (theguardian.com)
