Ex-president Armando Guebuza was on Thursday expected to testify in Mozambique’s biggest corruption scandal, an affair concerning secret loans contracted under his tenure that triggered an economic crisis. The AFP reports that the country, ranked among the poorest in the world, illicitly borrowed $2 billion in 2013 and 2014 from international banks to buy a tuna-fishing fleet and surveillance vessels, which the government masked the loans from the country’s parliament.
