The Russian president's most vocal critic died under mysterious circumstances while in prison in February – many blame Putin.
The former president whiffs on easy chance to criticise the Russian strongman.
The autocrat offered his own take on what happened to his most prominent critic.
It sparked speculation of a rift between the two prominent opponents to Putin's regime.
It follows widespread accusations that the Kremlin was involved in his death.
The crowd lining the streets in Moscow chanted "no to the war" in defiance of the Russian president.
"Putin is the leader of an organised criminal gang," Yulia Navalnaya said.
The late Kremlin critic also made a sad prediction for 10 years' time.
It's not just about what is happening on the frontline.
The body of Vladimir Putin's longtime foe is being hidden, his mother alleged.
