Navalny in a Russian court: What is he up against?

A court hearing is underway in Moscow, which could determine whether Russian opposition leader Alexei Navalny will have to spend the next several years in jail. Navalny has been in detention for violating probation since he returned to Russia from Germany, where he had been recovering from a poison attack he blamed on Kremlin forces. Outside the court, dozens of Navalny’s supporters have been detained by police.
