John Githongo is a former Kenyan journalist who investigated bribery and fraud in his home country and later, under the presidency of Mwai Kibaki, took on an official governmental position to fight corruption. In 2005 he left that position, later accusing top ministers of large-scale fraud. In the anglo-leasing corruption which he blew the lid over, fraudulent deliveries of government military and forensic laboratory equipment were allegedly ordered, "delivered" and the payment completed in the current president- Uhuru Kenyatta's tenure. The story of his fight against corruption is told in Michela Wrong's book It's Our Turn to Eat: The Story of a Kenyan Whistle-Blower.
