“Alexey Navalny, the anti-corruption blogger who for years has been Vladimir Putin’s only formidable opponent—which is to say, his only adversary who has remained in Russia, stayed active, and maintained prominence despite repeated attacks from the authorities—has been hospitalized in an intensive-care unit in the Siberian city of Omsk. He is in a coma. He fell ill aboard a plane, which then made an emergency landing. His assistant and press secretary, Kira Yarmysh, suspects Navalny has been poisoned.” The New Yorker: The Suspected Poisoning of Alexey Navalny, Putin’s Most Prominent Adversary.
