WASHINGTON (AP) - The White House says President Barack Obama and British Prime Minister David Cameron have discussed BP's need to do all it can to respond effectively to the oil spill in the Gulf of Mexico.
      
The two leaders spoke by telephone Saturday for about 30 minutes to discuss the oil spill, Afghanistan and other issues.
      
Obama has sharpened his attacks on BP as the company struggles to stop oil gushing from its ruptured deepsea well. Cameron is under pressure to get Obama to tone down the criticism fearing it will hurt the millions of British retirees that hold BP stock.
      
Cameron's office issued a statement about the BP discussion, saying Obama noted that BP is a multinational company and that frustrations about the spill had nothing to do with national identity.
      
BP formerly was known as British Petroleum.
