Russian opposition leader Alexei Navalny was poisoned with a dart frog toxin called epibatidine before he died in 2024, British Foreign Secretary Yvette Cooper said at the Munich Security Conference on Feb. 14.
“Only the Russian government had the means, motive and opportunity to deploy this lethal toxin against Alexei Navalny during his imprisonment in Russia,” she said. “Russia saw Navalny as a threat. By using this form of poison the Russian state demonstrated the despicable tools it has at its disposal and the overwhelming fear it has of political opposition.”
