But not Maria Pevchikh's (lead image, right) broadcast by the BBC's Russian Service.For the first time,; and Navalny's attempt to make political capital out of it, a modest success for the British secret services; an immodest failure for the German Foreign Ministry, Defence Ministry, German Army, and the Berlin medical clinic which goes by the name of Charity.The difference between the evidence of success and failure is the problem the BBC has attempted to overcome in an unusually long interview Pevchikh recorded with the BBC in Berlin, published on September 18 She is recorded as saying that she and her colleagues from the Navalny group had been having breakfast in the restaurant of their Tomsk hotel when they received the news that Navalny's flight to Moscow had been diverted to Omsk, and that he was in hospital with symptoms of poisoning.- three blue-capped bottles of Saint Springs water drunk by Navalny during the night before.The time shown on the wrist watch of Pevchikh, in the film she directed and released last week, 28 days after the event, shows a time. This wasand reported to his team in Tomsk, and to the rest of the world.Navalny's dogs were barking, but their caravan had failed to start according to plan.
