Guatemala is facing a political crisis that has seen tens of thousands march against repeated corruption scandals. The movement has toppled a plethora of high-ranking government officials. ‘The youth are not willing to tolerate the corruption that earlier generations have grown accustomed to,’ says Mario Polanco, a Guatemalan human rights activist.

The exposure – by a UN-backed anti-impunity commission – of a multi-million-dollar customs fraud scheme has led to the arrest of 20 state officials and the resignation of the vice-president and six ministers.
