Set up in the 1940s to ensure the world never again faced catastrophic economic recession, the International Monetary Fund has become a controversial presence in the management of the global economy. It is powerful, it is bossy and it is largely controlled by the USA and Europe. One of the IMF's top officials David Lipton, comes on to the show to answer the critics and to outline his vision for the IMF's future. He is joined by former IMF economist Professor Kenneth Rogoff and others who argue it's time for the IMF to reform to meet the needs of the 21st Century.
