Russian prosecutors seek 20-year sentence for Kremlin critic Navalny amid crackdown on dissent

Navalny is already serving 11.5 years in prison on charges he believes are politically motivated.
New charges accuse Navalny of extremism, creating an extremist organization, and illegally financing activities.
Navalny's trial has been held behind closed doors at the penal colony where he is imprisoned.
Verdict in Navalny's case expected on August 4 as part of Russia's crackdown on opposition figures.
Navalny is Putin's most prominent domestic critic and has accused the Kremlin of persecuting him for political reasons.
