Sobchak said he spoke to Chubais’ wife, who said “her husband’s condition is unstable. He felt bad very suddenly, he started not feeling his arms and legs.”
She directly quoted Chubais, who said of her condition: “I was hospitalized in one of the European clinics with a diagnosis of Guillain-Barr syndrome. Condition of moderate severity, stable.”
According to the United States Centers for Disease Control and Prevention, Guillain-Barré syndrome is a rare condition in which the immune system damages nerves in the body.
Chubais did not respond to a CNN request for comment and his current whereabouts in Europe are unknown.
Kremlin spokesman Dmitry Peskov said on Monday the Kremlin did not have details of what happened to Chubais, but said it was “sad news”.
Chubais left his post as the Kremlin’s special envoy for the environment in March. Reuters, citing two sources familiar with the matter, said he left the country due to the war in Ukraine. Chubais did not respond to CNN’s request for comment at the time. In March, the Kremlin confirmed that Chubais had quit his job. Chubais had held the environmental position since December 4, 2020, TASS said.
He rose to prominence as Boris Yeltsin’s finance minister in the 1990s. When Putin first came to power, Chubais was seen as an opponent by the current president. Putin claimed in a series of interviews in 1999 that Chubais canceled the Kremlin job he had originally been offered.
In recent years, Chubais continued to call for economic reform and was one of the few remaining liberals associated with the Russian government.
