LONDON: Britain and allies France, Germany, Sweden and the Netherlands are convinced that late Kremlin critic Alexei Navalny was poisoned with a lethal ‌toxin in a ‌penal colony ‌two ⁠years ago, they ⁠said in a joint statement on Saturday.

That was the conclusion of the five ⁠governments based on analyzes ‌of ‌samples from Navalny, ‌according to the ‌statement issued in London.

It added that the analyzes had conclusively ‌confirmed the presence of epibatidine, a toxin ⁠found ⁠in poison dart frogs in South America and not found naturally in Russia. The Russian government has denied any responsibility for Navalny’s death.
