Aleksei Navalny, the Russian opposition leader poisoned with a novichok nerve agent and airlifted for treatment to Germany, has emerged from his coma. The doctors treating him, however, warn that he has a long road ahead to recovery.
Germany's government said last week that tests on Navalny showed "unequivocal evidence" of the use of a chemical nerve agent from the Soviet-era Novichok group.
The attack on Navalny was met with widespread international condemnation, while the Kremlin has remained defiant in the face of global unease over Russia's role in the incident.
Navalny's team have pointed the finger of blame directly at Putin.
