The UK authorities are confident that they have clarified all the details of the assassination attempt and established the whole chain of people allegedly involved in the poisoning in Salisbury.
Experts Bellingcat noticed the similarity of Ruslan Boshirov, whom the British authorities consider involved in the poisoning of former GRU officer Sergei Skripal, with Colonel Anatoly Chepiga, awarded in 2014 the title of Hero of Russia.
The British authorities have traditionally suspected the Russian Federation.
The OPCW released the first results of the investigation into the "Skripal case".
Poisoning began at the threshold of their house in Salisbury.
The Prime Minister of Great Britain, Theresa May, considers the authorities of the Russian Federation either involved in the assassination attempt or having lost control over their chemical weapons.
