El Salvador's president Nayib Bukele was welcomed into the White House by President Trump earlier this week. The pair have recently become close allies after Trump began sending Venezuelan immigrations to a prison in El Salvador.  

On this Sky News Daily host Niall Paterson finds out who the self-proclaimed "world's coolest dictator" actually is. He speaks to chief correspondent Stuart Ramsay about what impact Bukele has had on El Salvador's gang problems and if he has transformed the country into a business and tourism haven.  

He also hears from Dr Ainhoa Montoya author and senior researcher at the Spanish National Research Council, and founding director of the Centre for Latin American and Caribbean Studies at the University of London. She explains how Bukele secured his position of power and uses social media as a propaganda tool.
