MOSCOW (Dow Jones)--BP PLC (BP), which intends to raise $10 billion worth by selling off assets in the wake of the Gulf oil spill, isn't planning to divest its stake in Russia's biggest oil producer, OAO Rosneft (ROSN.RS), BP's regional head told news agencies Friday. Speaking the day after Rosneft's stock fell almost 6% on speculation of an imminent sale by BP, David Peattie said the U.K.-based energy company hasn't sold and "isn't planning to" sell its stake. -By Will Bland, Dow Jones Newswires; +7 495 232 9198; william.bland@dowjones.com (END) Dow Jones Newswires June 18, 2010 05:14 ET (09:14 GMT)
