Longtime Putin Adviser and Russian climate envoy Anatoly Chubais has quit on his government and country. He is the first highest-ranking official to resign since the beginning of the invasion of Ukraine. The 66-year-old has also reportedly left Russia, citing his opposition to President Vladimir Putin’s war.

The long-time aid was very well-known in Russia as he was responsible for Russia’s privatization movements in the 1990s and served under Former Russian President Boris Yeltsin starting in 1991.

According to Russian news site TASS, Chubais left the post of special representative of the President of Russia and immediately left the country citing a source from Chubais’ entourage. He was appointed to the post in 2020 to achieve the goals of sustainable development after he had resigned from the Russian technology firm, Rusnano which he led since 2008.

After he left his job, Chubais was photographed by Newspaper Kommersant in Istanbul withdrawing money from an ATM. Russian Spokesperson Dmitry Peskov also confirmed the reports that he had left his post, but declined to say whether he has stayed in the country or had left.

“Whether or not he’s left the country — that’s a personal matter,” said Peskov in a report from Russian state news agency RIA Novosti.
