Andrew Roth “Putin adviser Anatoly Chubais quits and leaves Russia over invasion of Ukraine” https://www.theguardian.com/world/2022/mar/23/putin-adviser-anatoly-chubais-quits-leaves-russia-invasion-ukraine
Chubais is not a particularly influential member of the government and has no say in security affairs, but his resignation will create headlines in a country where most Russians know his name.
Chubais is best known as the architect of Russia’s controversial privatisation scheme in the 1990s, which helped create the country’s market economy but also concentrated immense wealth in the hands of a group of wealthy oligarchs.
A former chief of staff under Boris Yeltsin, Chubais recommended Putin for his first Kremlin position as deputy chief of the presidential staff in 1997, several years before he emerged as Yeltsin’s successor.
The former economist held a number of government roles during the 2000s, including the head of the state-run Rusnano firm. He was named Putin’s climate envoy in 2020.
In his years in government, Chubais established himself as a consummate political survivor, maintaining a role in Russia’s government despite his liberal credentials and the lingering anger over the pain of the Yeltsin government’s economic reforms.
Yet after Russia’s invasion of Ukraine began last month*2, he began to air signs of discontent, posting images of the slain opposition politician Boris Nemtsov*3 and that of the liberal economist Yegor Gaidar*4, who had warned of the dangers of imperial ambitions under Putin.
“In our arguments about Russia’s future I didn’t always agree with him,” Chubais wrote. “But it appears that Gaidar understood strategic risk better than I, and that I was wrong.”
