A civil society organisation, Socio-Economic Rights and Accountability Project (SERAP), has urged former President, Chief Olusegun Obasanjo, to disclose donations made to his presidential library.
It called on the acting President Yemi Osinbajo to propose a bill seeking to regulate fundraising for presidential libraries.
In a statement issued Sunday by its senior staff attorney, Timothy Adewale, SERAP said the bill, when signed into law, would ensure transparency in such donations.
Adewale said Osinbajo should work closely with the leadership of the National Assembly to ensure the speedy passage of any such bill into law.
He said: "The proposed bill would give Nigerians a better view of major donations going to presidential libraries, and provide access to information as to whether donors gain any special Aso Rock influence. The bill would minimise the potential for a quid pro quo, influence-peddling, and help to build trust and confidence among a citizenry that already questions the ethics of elected officials."
The statement read in part: "Proposing bill that would provide information to Nigerians and allow them to know those who help pay for presidential libraries is not only a matter of public interest but also crucially important to enhance transparency, accountability and strengthen this government's anti-corruption efforts.
"It's unfair to Nigerians for a sitting or former president to raise an unlimited amount of money for a presidential library and not to have the obligation to publish information on the major contributors. Without transparency into donations, a president could potentially take an official action in exchange for or in expectation of a future donation to his or her presidential library and the public would be unaware.
"Without openness and transparency, potential donors may seek to use library donations as a means to secure special access or political favours to authorities in Abuja.
"The proposed bill should include a requirement to disclose details about each contributor, the total value of each contribution, the source(s) of the contribution, and the date of each contribution. Any such information must be publicly and widely published, including on a website that is free for the public to access and that is searchable, sortable, and downloadable.
"The bill should also prohibit the making of a contribution through a corporation or other legal entity that may be used to conceal the identity of the person actually providing the contribution.
"Former President Olusegun Obasanjo would serve public interest by making a voluntary disclosure of every single donation, particularly large donations, to his newly launched presidential library. This would contribute to greater openness, something that the presidential library seeks to promote about the work and achievements of Obasanjo while in government."
