Oleg Deripaska, a close Putin ally, spoke to Russian reporters about the invasion of Ukraine, Reuters reported.
Deripaska, who faces international sanctions, cast doubt on Russia's hope of "victory" over Ukraine.
"I think that destroying Ukraine would be a colossal mistake, including for us," he said.
Oleg Deripaska, a billionaire aluminum tycoon and close Vladimir Putin ally, spoke out against the war in Ukraine on Tuesday while speaking with local journalists, suggesting there would be no winner following Russia's invasion, Reuters reported.
Deripaska, described by some as Putin's favorite industrialist, also lamented the economic impact of the invasion and subsequent sanctions, which he said have rolled back progress made by international business partnerships.

"I think that destroying Ukraine would be a colossal mistake, including for us," Reuters reported Deripaska said.
