Russian activist and Putin critic Alexei Navalny dies in prison

The Russian opposition leader Alexei Navalny has died in jail, the country’s prison service has said, in what is likely to be seen as a political assassination attributable to Vladimir Putin.

Navalny, 47, one of Putin’s most visible and persistent critics, was being held in a jail about 40 miles north of the Arctic Circle where he had been sentenced to 19 years under a “special regime”. In a video from the prison in January, he had appeared gaunt with his head shaved.

The Kremlin said it had no information on the cause of death.

In early December he had disappeared from a prison in the Vladimir region, where he was serving a 30-year sentence on extremism and fraud charges that he had called political retribution for leading the anti-Kremlin opposition of the 2010s. He did not expect to be released during Putin’s lifetime.

A former nationalist politician, Navalny helped foment the 2011-12 protests in Russia by campaigning against election fraud and government corruption, investigating Putin’s inner circle and sharing the findings in slick videos that garnered hundreds of millions of views.
