On Saturday, Mexico gets a new president. Andres Manuel Lopez Obrador - or AMLO as he's known. He won a landslide victory and now controls both houses of Congress. Born in poverty, AMLO is promising to eliminate corruption, champion the poor, and stand up to big business. His vision is not just government as usual but Mexico's 'fourth transformation', a kind of national renewal. He has already cut his own salary and that of senior civil servants and he has spooked the financial markets by cancelling Mexico City's new airport. But how realistic is his vision? The country is the second most unequal in Latin America, parts of it are controlled by drug traffickers and gripped by violence. And in his first week in power he'll have to deal with the migrant protest on the US border. So, will he change Mexico or will Mexico change him? Ritula Shah and a panel of expert guests profile Mexico's new president and discuss his vision and the challenges he faces.
