Nobel Winner Tutu Says No Longer an Oxfam Global Ambassador by Associated Press JOHANNESBURG -- Nobel Peace Prize winner Desmond Tutu says he will no longer be a global ambassador for the UK-based aid organization Oxfam after allegations that senior staff members in crisis zones paid for sex among the desperate people the group was meant to serve. A statement from the office of the South African former archbishop says he is "is deeply disappointed by allegations of immorality and possible criminality." The 86-year-old Tutu rarely makes public statements because of health problems. Actress Minnie Driver and Senegalese musician Baaba Maal also have quit as celebrity ambassadors for Oxfam following its response to a sex abuse scandal in Haiti after its 2010 earthquake.
