Exiled Russian tycoon Boris Berezovsky has been found dead at his home outside London.
A police investigation has been launched into the death of the 67-year-old - a wanted man in Russia, and an opponent of President Vladimir Putin.
A former Kremlin power-broker whose fortunes declined under Mr Putin, Mr Berezovsky emigrated to the UK in 2000.
Thames Valley Police said the death, at a property in Ascot, Berkshire, was being treated as unexplained.
... Last year, Mr Berezovsky lost a £3bn ($4.7bn) damages claim against Chelsea Football Club owner Roman Abramovich.
Mr Berezovsky claimed he had been intimidated by Mr Abramovich into selling shares in Russian oil giant Sibneft for a "fraction of their true worth".
The allegations were completely rejected by the London Commercial Court judge, who called Mr Berezovsky an "inherently unreliable" witness.
Suicide? Murder? Am I being a Conspiracy Theorist by thinking Mr. Berezovsky probably didn`t just keel over from a heart attack?
Back in 1989, I spent about six hours on a trans-Atlantic call negotiating a business deal with a minion of Robert Maxwell (the press baron initialed R.M. who wasn`t Rupert Murdoch). At the last moment, Maxwell intervened to try to cheat on a point already agreed upon, so my boss and I immediately broke off negotiations. Two years later, when I heard that Maxwell had fallen off his yacht, being an inveterate conspiracy theorist I assumed there was more to the story than just the slip in the dark that the Responsible Authorities agreed upon before Maxwell`s vast embezzlement of his workers` pensions was discovered.
