The widow of Alexander Litvinenko has submitted a claim against Russia to the European court of human rights (ECHR), seeking €3.5m (£3.1m) in compensation for his murder by radiation poisoning in London.
Marina Litvinenko is requesting punitive damages and payment for accumulated lost income. A public inquiry concluded that her husband’s murder in 2006 was probably ordered by Vladimir Putin.
The submission also asks the Strasbourg judges to rule on the significance of the pattern of targeted assassinations and attempted killings allegedly carried out by Russian state agents across Europe and the Middle East.
Among the attacks listed are the 2018 poisoning of Sergei Skripal and his daughter Yulia in Salisbury and the subsequent death of Dawn Sturgess after she handled a discarded container filled with the nerve agent novichok.
