Boris Berezovsky is having a hell of an afterlife. On Wednesday, Russian Attorney General Yuri Chaika stated that Berezovsky “paid with his life” for allegedly wanting to repatriate in 2013, supposedly “with the secret of who really killed Alexander Litvinenko.” “When he decided to return to Russia, [British intelligence] couldn’t allow someone with secrets about an act of nuclear terrorism to return to Russia,” Chaika said, referring to the polonium used to poison and kill Litvinenko in 2006.

The attorney general also said that the largest concentration of polonium was discovered in Berezovsky’s office — evidence, Chaika argues, that he must have been working with British intelligence to have gained access to so much of the rare element.

British officials believe that Russian intelligence is responsible for organizing the murder of Litvinenko, a former FSB agent. The man who allegedly delivered the poison was Andrey Lugovoi, who’s served in the State Duma since 2011.

Berezovsky fled to London in 2001. Two years later, Moscow demanded his extradition on fraud charges, but the UK refused and instead granted him political asylum. In 2006, Russian police opened another case against Berezovsky, accusing him of inciting an armed revolution against the Kremlin. The same day Berezovsky was found dead in Berkshire on March 23, 2013, Vladimir Putin’s spokesman revealed that Berezovsky had written the president a letter “begging forgiveness” and asking to return to Russia.
