Alexei Navalny is the long-time leader of Russian opposition. Because the Russian dictator Putin tolerates no opposition, there has been a long record of various attacks against Navalny, his famiy members (e.g. his brother has served a prison sentence), and his supporters. Last year, Mr. Navalny narrowly survived a poisoning attempt, and was treated in Germany for months. The doctor who gave him first aid in the city of Omsk and most likely saved his life has meanwhile died, the death attributed to a heart attack. Alexei Navalny eventually returned to Russia, was immediately arrested, and has already been convicted to 3.5 years in prison on made-up charges.
Amnesty International initially gave Mr. Navalny a "prisoner of conscience" status, but has now revoked it because of unspecified "comments he made in the past" that "reach the threshold of advocacy of hatred". These comments have not been specified, but are supposedly from speeches against immigration, especially illegal immigration, held more than a decade ago.
Alexander Golovach, a supporter of Navalny who had been declared prisoner of conscience in 2018, has now renounced this status to protest.

Update: I have just shared this news with my husband, who follows closely the situation in Russia (I have no nerve for this). His comment: "I can tell you that Putin is great. His tentacles are everywhere, see how far they reach!"
Update 2: Tom Tugendhat, the chairman of Britain's Foreign Affairs Select
Committee, made a spot-on comment: “If Amnesty will only call out the persecution of
saints, they’re siding with tyrants. The prisons will be full and they
will stay silent as ordinary, flawed human beings are persecuted for
crimes of conscience.” Read the whole report by Robert Oliphant at the Telegraph.
