June 18 Bloomberg — BP Plc, which has shed 45 percent of its market value after causing the U.S.’s worst-ever oil spill, said it will keep sponsoring the British Museum, the Royal Opera House, Tate Britain and the National Portrait Gallery in London.

“These are longstanding partnerships that we have with major cultural institutions in the U.K.,” BP spokesman David Nicholas said in a telephone interview yesterday. “They’re completely unchanged, as far as I’m concerned.”
