Sir Michael Barber - Chief Education Advisor, Pearson PLC
Despite the United Nations' hopes of a primary education for every child in the world by 2015, around 69 million children are still not getting an education. Michael Barber has advised governments around the world about education. He's now working for the international company Pearson which has recently announced it would invest millions in private schools for the world's poorest families. Is that the right way to tackle the problem or could it undermine what governments are trying to do?
