ABUJA Nigeria has accepted an international survey which ranked Africa's most populous country as the most corrupt in the world, and pledged to make amends, AFP said. Finland was judged the least corrupt country and Nigeria the most in a survey of 90 nations by the non-governmental organization Transparency International (TI), released in Berlin on Wednesday. "Indeed, we are guilty," said Alphonsus Nwosu, a special adviser to President Olusegun Obasanjo here late Thursday. He said the government will not be deterred by the ranking, but will do everything to eradicate the menace of corruption from the country.
