 The son of Mozambique's ex-president Amando Guabusa, on Monday night allegations he took bribe to facilitate a $2 billion secret government loan, the loan that plunged the southern African country into a financial crisis. Guabusa's elder son, Ndambi, is among 19 high-profile defendants facing trial in a high-security prison in the capital Maputo. The 2013 corruption case is known as the Hidden Debt Scandal. He is accused of receiving $33 million from an international shipbuilding group, Privinvest. The aim is to convince his father, who was president at the time, to approve corrupt maritime projects. In 2013 and 2014, three public companies secured $2 billion in state-guaranteed loans from international banks. They were to buy a tuna-fishing fleet and surveillance ships, which they contracted to Privinvest. An independent audit later found that $500 million of the loans which were kept hidden from parliament remains unaccounted for. Privinvest has previously denied wrongdoing.
