BP tops the agenda as Barack Obama hosts Britain's new prime minister David Cameron for talks

British Prime Minister David Cameron continues his first visit to the US since taking office today... with a trip to the Pentagon and the United Nations on the agenda. So far, his visit has been overshadowed by controversy surrounding British oil giant BP. In addition to the Gulf of Mexico oil spill, BP is now also accused of having lobbied for the release of the Lockerbie bomber. The issues dominated his first official meeting with US President Barack Obama.
