U.S. President Barack Obama will meet with British Prime Minister David Cameron Tuesday in the British leader's first official trip to the United States, aides said. Cameron and Obama have a slate of issues to discuss, including the British government's decision to establish a 2015 end date for Britain's combat role in Afghanistan, a drastic British deficit reduction plan and the Gulf of Mexico oil spill, The New York Times was quoted as reporting by the United Press International (UPI). Cameron's two-day visit also will involve meetings in New York with Mayor Michael Bloomberg and Wall Street executives, officials said.
