Russian President Vladimir Putin stands next to First Executive Vice President of oil producer Lukoil Ravil Maganov after decorating him with the Order of Alexander Nevsky during an awarding ceremony at the Kremlin in Moscow, Russia, on Nov 21, 2019.
Reuters was unable to confirm those details. Three sources told Reuters that, based on their close acquaintance with Maganov, they did not believe he would have killed himself. Lukoil is a private company that competes with Russian state energy giant Rosneft . It said in a statement that Maganov had "passed away following a serious illness".
The deaths were all in Russia apart from that of Sergei Protosenya, a former top manager of Russia's largest liquefied natural gas producer Novatek, who was found with the bodies of his wife and daughter at a villa in Spain. Catalan regional police, investigating the case, have said they believe he killed them and then took his own life.
