Boris Berezovsky said his life had no meaning in Forbes interview

Boris Berezovsky, a former power broker for the Kremlin who was exiled from Russia, has been found dead in his home in Surrey.

An influential businessman who rose to prominence in the 1990s by breaking up Russia's state sectors, Berezovsky had been the target of several assassination attempts in the past. 

The investigation into his death was still underway Sunday, with chemical, biological, radiological and nuclear experts giving his home the all-clear, reported the Guardian.

Though there were reports that Berezovsky may have committed suicide, some continue to insist that the Kremlin critic was assassinated.

Just before his death, the Russian oligarch was interviewed by Forbes Russia.

During the interview he said he wanted to return to Russia and he felt that his life had no meaning.

He also said that he felt uncomfortable in Britain.

It was also reported that the billionaire was depressed after losing a court cause with Russian oligarch Roman Abramovich, whom he accused of blackmail.

The case was dismissed by a British court and Berezovsky was forced to pay over $50 million in Abramovich's legal costs.

Berezovsky was known for using his charm and political connections to secure deals and investments, the Telegraph reported in their obituary.

“Privatization in Russia goes through three stages," Berezovsky said in 1995. “First, the privatization of profit; second, privatization of property; third, the privatization of debt."  

The 67-year-old tycoon had been living in the UK since 2000, BBC News reported. He died in his bathtub. 

Sky News is reporting that his death was a suicide.
