Russian President Vladimir Putin's former adviser and Soviet-era dissident Gleb Pavlovsky died on Monday at the age of 71 after a prolonged illness, his family said.
An influential figure in Russia's post-Soviet political architecture and in Putin's initial tenure, Pavlovsky turned critic of the Russian president after his adviser contract was terminated in 2011.
"Relatives and friends of Gleb Pavlovsky express their deep gratitude to everyone who supported and helped all these months, went through all of this with us, endured, understood and protected," the family said on Pavlovsky's Telegram messaging channel.
