Berezovsky & Trotsky

As I've pointed out, Russia's leader Vladimir Putin is the patron of Russia'a oligarchs. The Russian oligarchs that remains, that is. When Putin established his current semi-dictatorship, he made sure to dispose, one way or another, of all oligarchs that opposed him, such as Boris Berezovsky and Mikhail Khodorkovsky. Berezovsky was exiled in a manner similar to how Joseph Stalin exiled Leon Trotsky and Khodorkovsky was jailed on charges which was probably true, but wouldn't have been put forward if he had pledged his allegiance to Putin. Now Berezovsky, who was exiled in a manner similar to Trotsky's, suddenly dies in exile for unknown causes. Most likely an ice axe wasn't used, as it was in Trotsky's case, and it is of course possible that Putin wasn't involved at all. But the similarity of a key opponent that was exiled and then died are too clear not to at least awaken some suspicion...
