Russian opposition leader Alexey Navalny dupes spy into revealing how he was poisoned : worldnewsDecember 21, 2020
The following text is from the article. All added emphasis (bold) and comments (unquoted text) is mine:
A Russian agent sent to tail opposition leader Alexey Navalny has revealed how he was poisoned in August — with the lethal nerve agent Novichok planted in his underpants.
The “he” here being Navalny
The stunning disclosure from an agent who belonged to an elite toxins team in Russia’s FSB security service came in a lengthy phone call following the unmasking of the unit by CNN and the online investigative outfit Bellingcat last week.
In what he was told was a debriefing, Konstantin Kudryavtsev also talked about others involved in the poisoning in the Siberian city of Tomsk, and how he was sent to clean things up.
Kudryavtsev = the agent.
But the agent was not speaking to an official in Russia’s National Security Council as he thought. He was talking to Navalny himself, who almost died after being poisoned in August.
