Nigeria's new Transport Minister Rotimi Amaechi smiles during a swearing-in ceremony in Abuja, Nigeria November 11, 2015. Nigeria's President Muhammadu Buhari swore 36 ministers into his cabinet on Wednesday, five months after his inauguration. Buhari won March elections after vowing to crack down on corruption in Africa's biggest economy and top oil producer. He has been criticised for waiting until September to name his ministers at a time when the economy has been hammered by the fall in oil prices. REUTERS/Afolabi Sotunde - GF20000054922
