LONDON -- A British coroner has recorded an "open verdict" on the death of Boris Berezovsky, saying it was not possible to conclude whether the self-exiled Russian tycoon was killed or committed suicide.

At the end of a two-day inquest, coroner Peter Bedford said he could not be sure beyond reasonable doubt of the circumstances of Berezovsky's death.

The 67-year-old Berezovsky -- a Kremlin insider-turned-critic of President Vladimir Putin -- was found on a bathroom floor of his ex-wife's home in southern England in March 2013. A ligature was around his neck.
