Alexei Navalny is Russia's best-known anti-corruption campaigner and opposition activist. Today he lies gravely ill in a Berlin hospital. The German doctors treating him say he appears to have been poisoned. Navalny has been a longstanding critic of President Vladimir Putin, and his anti-corruption activities have highlighted the huge asset holdings of Russia’s political elites. His online activism draws tens of thousands of people to the streets across the country in protest against a range of injustices. So what do we know about what has happened to Mr Navalny and his recent activities? Will his hospitalisation galvanise the opposition? And what of the timing - can the Kremlin afford a backlash now when Russia’s closest neighbour, Belarus, is gripped by anti-regime protests? Ritula Shah is joined by a panel of expert guests to discuss how events have changed the picture in Russia.
