A judicial inquiry will open in Windsor today into the death of Russian oligarch Boris Berezovsky to establish how he died in his vast mansion.
The 67-year-old was found dead on Saturday in his home in Ascot and Police said his injuries were "consistent with hanging".
"If he really hanged himself why was that not known from the very beginning?" said Andrei Sidelnikov, a friend of Berezovsky.
"I don't believe it was a suicide."
