Peter Eigen, Anti corruption campaigner

Peter Eigen has fought corruption for decades, but the problem seems to be as big as ever. Originally a banker, he set up Transparency International, to publicise the extent of bribery. Now, he's trying to combat the 'resource curse', where the citizens of poor countries do not see the benefits of the huge revenues earned from minerals, oil and gas.

Jonathan Charles asks Peter Eigen if he is disheartened by the fact that corruption in international business is still so prevalent.
