Vladimir Putin’s ‘primary enemy’ Alexei Navalny was killed with a poison developed from a dart frog toxin on the Kremlin’s orders, Britain and its allies have revealed.
The Russian opposition leader died at a Siberian penal colony in 2024 after accusing the president of corruption.
Two years on, the UK and its allies have pinned the blame on the Russian state following evaluation of fabric samples found on his body.
The Russian authorities have previously strenuously denied any involvement in his death.
However the UK Foreign Office said there is no such thing as a innocent explanation for the toxin Epibatidine being found on Mr Navalny’s body.
Foreign Secretary Yvette Cooper has met with Mr Navalny’s widow Yulia Navalnaya on the Munich Security Conference this weekend.
Mrs Navalnaya announced her husband’s death on the gathering in 2024.
Ms Cooper said: ‘Since Yulia Navalnaya announced the lack of her husband here in Munich two years ago, the UK has pursued the reality of Alexei Navalny’s death with fierce determination.
‘Only the Russian Government had the means, motive and opportunity to deploy this lethal toxin against Alexei Navalny during his imprisonment in Russia.
‘Today, beside his widow, the UK is shining a lightweight on the Kremlin’s barbaric plot to silence his voice.
‘Russia saw Navalny as a threat.
‘Through the use of this type of poison the Russian state demonstrated the despicable tools it has at its disposal and the overwhelming fear it has of political opposition.’
A joint statement by the British Government and its allies in Sweden, France, Germany and The Netherlands said the nations ‘are confident that Alexei Navalny was poisoned with a lethal toxin’.
They plan to submit their findings to the UN’s chemical weapons watchdog, the Organisation for the Prohibition of Chemical Weapons (OPCW).
The statement said: ‘That is the conclusion of our Governments based on analyses of samples from Alexei Navalny.
‘These analyses have conclusively confirmed the presence of epibatidine.
‘Epibatidine is a toxin present in poison dart frogs in South America.
‘It just isn’t found naturally in Russia.
‘Russia claimed that Navalny died of natural causes.
‘But given the toxicity of epibatidine and reported symptoms, poisoning was highly likely the reason for his death.
‘Navalny died while held in prison, meaning Russia had the means, motive and opportunity to manage this poison to him.’
The allies also pointed to an try to poison Mr Navalny with the nerve agent Novichok in 2020, which followed the Salisbury poisonings in 2018.
‘Russia’s repeated disregard for international law and the Chemical Weapons Convention is obvious,’ the five nations said.
They added: ‘In each cases, only the Russian state had the combined means, motive and disrespect for international law to perform the attacks.’
The Foreign Office also insisted that Russia had not destroyed all of its chemical weapons, as Moscow claimed it had done in 2017.
Britain will proceed to show the Kremlin’s use of chemical and biological weapons, the Foreign Office added.
