LONDON (AFP) -- U.S. President Barack Obama told British Prime Minister David Cameron Saturday that the president's sharp criticism of BP (BP, BP.LN) has "nothing to do with national identity," Downing Street said. Obama also stressed that he had "no interest" in undermining the British oil giant, in a 30-minute phone conversation between the two leaders. The president's rhetoric has sparked fears that he was stoking an anti-British backlash over the Gulf of Mexico oil spill. (END) Dow Jones Newswires June 12, 2010 13:07 ET (17:07 GMT)
