British Prime Minister David Cameron sometimes works in his pajamas LONDON, June 15 (UPI) -- British Prime Minister David Cameron says he often works in his pajamas because he starts work so early in the morning. While speaking on BBC radio and television, Cameron was asked by a member of the public if he ever works in his pajamas, because he lives and works in the same building, The Daily Telegraph reported Friday. "Yes, I suppose I do," Cameron answered. I get up pretty early in the morning and I start work before I get dressed.
