Alexey Navalny is a Russian opposition leader and anti-corruption activist known for his criticism of the Russian government and President Vladimir Putin. He gained prominence through his investigations into government corruption, which he published on social media and his website. Navalny has faced multiple arrests and legal challenges, which many view as politically motivated. In 2020, Navalny was poisoned with a nerve agent, an act widely attributed to the Russian state. After recovering in Germany, he returned to Russia in early 2021, where he was immediately detained. His imprisonment has sparked international condemnation and protests in support of his cause.
