A sudden political scandal in Lima may already be harming Peru's economic outlook. Why do Latin American countries seem so economically fragile and prone to populism? Daniel Gallas reports from an apoplectic Peru, where many people suspect President Pedro Pablo Kuczynski of cutting a deal with the opposition to free former President Alberto Fujimori from jail, in return for the current president escaping impeachment over the Odebrecht corruption scandal. Presenter Ed Butler speaks to political analyst Richard Lapper of Chatham House about the populist tide sweeping across the continent, while economist Nestor Castaneda of University College London explains why the root cause may be excessive economic dependence on commodity exports. Also, Jeremy Wagstaff of Reuters describes the potential role for Blockchain technology in sharing sensitive information.
