Alexei Navalny’s lawyer has confirmed that the opposition leader is “seriously ill” after reports emerged that he had been transferred to a prison sick ward for a respiratory illness and had been tested for coronavirus. The Kremlin critic said in a note published on Monday that he was coughing and had a temperature of 38.1C (100.6F). Several prisoners from his ward had already been treated in hospital for tuberculosis, Navalny wrote. Hours later, the pro-Kremlin newspaper Izvestia reported he had been moved to a sick ward and tested for coronavirus, among other diseases.
