BP appoints new global refining VP

BP PLC said that London-based global refining vice president Mike Hoffman would leave the company on April 30 to return to the United States, his home country. The company said Hoffman will be replaced by C.J. Warner, a regional vice president for health, safety and the environment. BP has had a tough 18 months in the United States, suffering a series of operational and governance problems that have led to strong criticism from investors and a dent in its reputation for good governance.
