President Muhammadu Buhari on Friday signed eight bills earlier passed by the National Assembly into law.

The Act grants members of Legislative Houses in the National Assembly and State Houses of Assembly immunity from litigation for actions taken in plenary or committee proceedings of the House or committee.
According to Enang, the law is meant to strengthen the power of the legislators to carry out their legislative functions.
The powers include powers to summon any person to appear before her, give evidence, including power of an officer of the legislative House to arrest any person who commits an offence against the Act.
The Act, establishing the institute, widens her powers to include powers to provide training courses and award degrees on democracy, party politics, electoral process, legislative practice and procedures among others.
Another law the President assented to was the National Senior Citizens Centre Act, 2018.
The Act establishes the National Senior Citizens Centre in the country to cater for the needs of senior citizens.
