Love for you to post what he said but you wont/cant. The west first said poison through skin contact (underpants) on flight from tomsk to moscow then it became through ingestion with a bottle of water “found” in his hotel room days after he checked out. Which hotel leaves the previous guests rubbish in the room for the next guest?
To believe the western narrative you would have to believe the poisoners, as in the cases of Navalny and the Skripals are spectacularly incompetent in using one of the most toxic substances on earth.
PS - skripals have vanished. No one has seen him or his daughter. You would think western media would be all over them with interviews telling their story of putins evil
