The parliament was preceded by the Legislative Council of Nigeria[2] established in 1946.[3] The Macpherson constitution of 1951 expanded the council furthermore by creating a 185-seat federal House of Representatives.[4]
Independence parliament
The system was slightly adjusted after the proclamation of the republic in 1963.[5]
The Federal Parliament was the legislative branch of the government, consisting of three elements: The President, the Senate (the upper house) and the directly elected House of Representatives (the lower house).[6] Each had a distinct role, but work in conjunction within the legislative process. This format was inherited from the United Kingdom and was a near-identical copy of the Parliament at Westminster.
Senate
The Senate was modelled after the British House of Lords and the Canadian Senate. It had 20 members, twelve of which represented the each region and were nominated by an electoral college of their regional assembly. four were appointed by the President on the advice of the prime minister and the remaining four individuals represented the Federal Territory: the Oba of Lagos (an ex officio Senator), a chief selected by parliament, two other individuals.[7][8]
House of Representatives
The elected component of Parliament was the House of Representatives. To run for one of the 305 seats in the lower house, an individual had to be at least 40 years old. Each member holds office until Parliament was dissolved, after which they may seek re-election. Only those who sit in the House are usually called members of Parliament (MPs).[9]
