The resignation of Kremlin special envoy Anatoly Chubais over the invasion of Ukraine is encouraging but is unlikely to shake Russian President Vladimir Putin's firm grip on power, a Western official said on Wednesday.
The official said that the resignation of Chubais, the architect of Russia's post-Soviet economic reforms who once served as former President Boris Yeltsin's chief of staff, was a "significant statement" but added he was "relatively high up on the list" of people who might make such a step.
