Moscow points the finger of blame at billionaire exile Boris Berezovsky

The Kremlin mounted a concerted campaign yesterday to point the finger of suspicion at the billionaire businessman Boris Berezovsky over the death of his friend, Alexander Litvinenko, after traces of radioactive polonium-210 were found at the London offices of the exiled Russian oligarch.

Senior figures in the Russian establishment lined up to implicate Mr Berezovsky, who employed and funded the former KGB spy.
