Alexander Petrov and Ruslan Boshirov, whom the British accuse of poisoning the Fiddles, often visited Europe and met repeatedly with an unknown person in Geneva. This was told by sources in the UK government. It is noted that in Switzerland they spent several weeks.

At the same time in London, they believe that they contacted the curator. This information, according to the authorities, can become an "absolute key" to the ongoing investigation, the newspaper The Telegraph. In addition, the British claim that the names of "poisoners" were known before, but the intelligence services collected the necessary evidence to report this to the whole world. On 4 March, the former GRU colonel and his daughter were hospitalized in the English town of Salisbury unconscious. The British side accused Russia of what had happened. The latter categorically denies his involvement in the incident, which almost every day is covered with new details.

Moscow has repeatedly offered its assistance in the investigation, but London in every possible way disavows Russian intervention. The so-called "business of Skripal" provoked an international scandal. Disagreements between Moscow and the West led to an exchange of diplomats and sanctions. On the eve of the British showed photos of suspects in the attempt. These are two officers of the GRU: Alexander Petrov and Ruslan Boshirov. These names "do not say anything", so reacted to information in the Kremlin and once again called on "prosecutors" to cooperate.
