According to the Nigerian Constitution, a National Assembly made up of a Senate and a House of Representatives has the authority to pass laws on behalf of the Federal Republic of Nigeria. Laws promoting stability, law and order, and effective governance may be passed by the National Assembly. However, lobbying and zoning have had an impact on the present leadership, which is led by Ahmed Lawan and Femi Gbajabiamila. The legislature is expected to endeavour to rein in executive excesses and assure equitable representation because it is modelled after the federal Congress of the United States. With 59 senators and 50 opposition parties, the 9th National Assembly has 66 seats in the Senate and 227 in the House of Representatives. The assembly struggles to establish itself as an independent body, and the ruling party is unable to compel a candidate.
