If found guilty, Nadezhdin won’t be able to run in the elections, his lawyer Dmitry Trunin said on Telegram. “Until Friday, I’m completely free!” Nadezhdin wrote in his Telegram channel, attaching a picture of the court order. He is one of the few Kremlin critics in Russia who publicly criticises Putin’s rule and Moscow’s Ukraine war who is not in prison or exile. The arrest came three days after authorities declared Nadezhdin a “foreign agent” – a tag used by the Kremlin to stifle dissent. Nadezhdin, who was an MP in the early 2000s, has been gathering signatures to register as a candidate for lower-house elections in September. The vote will take place in a fifth year of war, with Ukrainian strikes affecting ordinary life more than ever.
