Nigeria is ranked as one of the most corrupt countries in the world.
Daily, low-level corruption is visible on the street; policeman extorting money from motorists to supplement their meagre wages. But it is in the world of politics and government, where corruption has been most damaging. For decades the government has accrued huge oil revenues, yet the country suffers from a lack of basic infrastructure, and tens of millions live in poverty. At the same time, some politicians and their business associates have amassed personal fortunes.Although accusations of graft have long been a feature of Nigerian politics, as elections approach early next year, the politics of corruption have taken on a new powerful role.
