An appeals court confirmed Tuesday a nine-year prison sentence for Russia’s most prominent Kremlin critic Alexei Navalny.

In March, Navalny was found guilty of embezzling funds for his anti-corruption foundation and insulting a judge during a previous trial, a sentence that added nine years to his time in prison.

"The Moscow City Court upheld the verdict of the Lefortovo court in the case of Alexei Navalny. Nine years in a strict regimen colony," his partners wrote on Telegram.
