Is the EFCC, headed by Nuhu Ribadu (above) only targeting opponents of president Obasanjo?
Jonathan Charles talks to the Head of Nigeria's Economic and Financial Crimes Commission.
Nigeria's president, Olusegun Obasanjo, established the Economic and Financial Crimes Commission four years ago to root out the country's endemic corruption.
The commission has been praised for making a difference, but as the April elections draw near, critics are accusing the president of using the EFCC to discredit his opponents.
Jonathan Charles talks to the EFCC Chairman, Nuhu Ribadu.
Will his efforts to rid his country of corruption amount to anything, or is he being used as a political pawn?
