Chubais had a hand in economic reforms that followed the collapse of the Soviet Union but remained in Putin’s government and had maintained close ties with Western officials.

In response to the faltering invasion, Putin has now reportedly placed General Vladislav Yershov under house arrest.

Under his command, the 6th Army has lost 2000 soldiers including 180 conscripts doing national service, says Ukrainian media.

He was sacked by Defence Minister Sergei Shoigu, who himself has not been seen for 12 days and is said to be suffering from “heart problems”.
