Mikhail Khodorkovsky, once Russia's richest man before he fell foul of the Kremlin, said on Friday that only revolution would topple Vladimir Putin, and he expected the Kremlin chief to crack down further on dissent at home after invading Ukraine.
Khodorkovsky, who under President Boris Yeltsin in the 1990s became one of Russia's most powerful oligarchs, said he doubted that the Russian people supported the invasion.
