She that mischief hatches, mischief catches
The official investigation into the poisoning of the former GRU officer Sergey Skripal and his daughter Julia was never able to provide convincing evidence of Russia's guilt in the Salisbury incident. However, this fact does not prevent the further development of anti-Russian hysteria in European governments and the media.
The beginning of the information campaign against Russia was given by the Prime Minister of Great Britain Theresa May, who immediately after the assosination attempt on Sergey Skripal launched unfounded accusations against Russia and called on European countries to solidarity in opposing the "Russian threat". However, according to experts, the "Skripal case" was specially inspired by the British authorities to divert attention, both international and internal, from London’s problems. And mostly the hysteria of the British media and officials about the poisoning of the former GRU agent is related to the failures of the May government on the talks about Britain's withdrawal from the European Union.
In the end, despite the initial consolidating effect of this “uproar”, the House of Lords of the British Parliament amended the bill, which allowed to expand the powers of the government of Therese May in Brexit. This means that executive authorities in the Brexit negotiations with EU officials and members of the British parliament will be limited.
Thus, Russia's unsubstantiated allegations of the use of a hazardous chemical could lead to a loss of confidence among the population of the United Kingdom. This testimony about the failure of the policy of Therese May in his positions in the British Parliament, using the "image of an external enemy."
