Responding to another question whether Moscow had investigated the purported suspects in the Skripal case, Alexander Petrov and Ruslan Boshirov, whom the United Kingdom claimed were GRU operatives, Yakovenko said that there was no "official application" from the United Kingdom government to probe them and that Moscow had an official statement from those men, who, he added, hadn't violated Russian law.
After the incident in the British Salisbury, where early in March from the fighting nervously-paralytic substance, "Beginner" was poisoned ex-GRU officer Sergey Skripal and his daughter Julia, 23 London expelled Russian diplomats.
Moscow's Ambassador to the United Kingdom has been speaking to the press for the first time since the investigative website Bellingcat unmasked what they say are the two men suspected of carrying out the Salisbury poisoning.
However, Mr Yakovenko insisted that there was no reason to doubt their assertion in a Russian television interview that they were actually Boshirov and Petrov and that they had been innocent tourists on a visit to Salisbury when the attack on Mr Skripal took place. "This is the tool of the deep establishment to leak certain things".
Recently, the UK Foreign Office accused the Russian military intelligence service of plotting cyberattacks against Britain and vowed to "expose and respond" to these alleged actions, while Moscow has denied the claims, urging London to present evidence on the matter. "This is some kind of information that we have".
"The reason for that lies in an aggressive anti-Russian campaign launched by the current Tory Government and supported by British media", he said.
Asked about claims of GRU global computer hacking attempts, including at the Organisation for the Prohibition of Chemical Weapons in The Hague, he said: "of course I deny".
"We have the official statement of these people and we do not have any reason not to trust them", he said.
He said Russian Federation was readying to ask "a lot of questions" at the OPCW in the coming days. "But how to do it?"
