LONDON (AP) — In a span of a decade, Alexei Navalny has gone from the Kremlin’s biggest foe to Russia’s most prominent political prisoner. Already serving two convictions that have landed him in prison for at least nine years, he faces a new trial that could keep him behind bars for two more decades. He has been locked up in solitary confinement repeatedly. He says the charges that initially sent him to prison were politically motivated, aiming to stop his anti-corruption campaigns as well as hindering his runs for office. He also was poisoned with a Soviet-era nerve agent, blaming it on the Kremlin — accusations that Russian officials deny.
