The poisoning in Salisbury of ex-colonel GRU Sergey Skripal with the help of nerve agents was prepared by a group of six people called "Cleaners". This was reported by the Daily Mirror with reference to a source in the security services of Great Britain. In addition to the names of two allegedly Russian spies who participated in the attempted assassination of Skripal and his daughter Julia, Alexander Petrov and Ruslan Boshirov (identified after watching 11 thousand hours of outdoor video films), four other people were involved in the operation,. Petrov and Boshirov flew to London Gatwick Airport on March 2, and the "reserve team" arrived in the UK via other air harbors at about the same time. They used in the documents the data of real prisoners who are in prisons on the territory of the European Union. "A support group was needed to watch the Fiddles. Petrov and Boshirov should have known that Skripali would not return home while they were processing the door with the "Novice", "the source said.. It is noted that Petrov and Boshirov made a series of trips to the United Kingdom a year before the attempt to create a passport trace - so that their journey of a real attack did not cause suspicion. The source noted: "The classic cover is rich Russians who are interested in property".

Recall, September 5, the British authorities said that the violins were poisoned by two GRU officers under pseudonyms Alexander Petrov and Ruslan Boshirov. The American New York Times on September 7 wrote that Skripal collaborated with Spanish, Czech and Estonian intelligence. Perhaps he provided information on Russian organized crime, including on groupings that may be associated with the Russian authorities. Moscow denies all charges of London and regularly calls for a joint investigation of the incident in Salisbury.
