Britain's former Prime Minister Tony Blair poses for a portrait following a Reuters Television interview in central London April 1, 2010. Blair on Thursday added his voice to calls for African development strategies to go beyond aid, saying a predictable and transparent business environment was critical to sustainable development. Blair, whose African Governance Initiative advises three African governments, said developing countries needed to do more to promote government accountability, battle graft and create a "one-stop shop" for frontier investors.
