One of the founding fathers of the beleaguered Yukos oil company, Yuri Golubev was found dead in his London apartment Jan. 7, The Moscow Times reported Jan. 11. Though the cause of death has not been determined, Golubev's associates say they do not believe it was suspicious. The mysterious death by polonium poisoning of former Federal Security Service agent Alexander Litvinenko in London in November 2006, however, means the circumstances surrounding the deaths of prominent Russian Kremlin opponents will come under greater scrutiny. Golubev founded and helped shape Yukos before it was bought by Mikhail Khodorkovsky's Menatep Group. Khodorkovsky kept Golubev on as one of his closest advisers.
