Boris Berezovskij dead - a new Litvinenko?

[HoreTore]

Found dead in his bathtub. Identity confirmed by his lawyer and a relative. British police has started an investigation, and has classified the death as unexplained.

A quick bio for those who may not know who he was:

Boris Berezovskij rose as one of Russia's top oligarchs after the USSR, through control and ownership of car industries, Aeroflot, Channel One, oil companies and much else. He was a close supporter of Boris Jeltsin, and used his control of Channel One, Russia's primary television channel, to aid his re-election. He also supported Putin's rise to power, but their relationship soured in 2000. Berezovskij was accused of several crimes, and fled to the UK where he was granted political asylum. He propagated the conspiracy theory that the apartment block explosions in Moscow, which was used to justify the 2nd Chechen war, was done by the FSB. At the time of his death, he was wanted under suspicion of planning a state coup.

What is the Backroom's opinion of this? Another radioactive diplomatic scandal in the makings?
