International condemnation is growing over the arrest of Russian opposition leader Alexey Navalny after his return to Moscow.
Navalny spent the last five months in Germany after he was poisoned in an attack he said was ordered by President Vladimir Putin.
The United States, the United Kingdom and the European Union are calling for his immediate release.
Germany has described Navalny’s arrest as incomprehensible, while Amnesty International accuses Russia of waging a “relentless campaign” against him.
So, just how much of a challenge is Navalny to President Putin?
