The presidency is expected to sign the 2017 budget into law next week, the speaker of the lower chamber of parliament, Yakubu Dogara, and two presidency sources said on Friday.
The record 7.44 trillion naira budget passed by parliament on May 11 was bigger than the 7.298 trillion naira draft spending plan submitted by Buhari in December.
The budget must be signed by the president to become law. President Muhammadu Buhari has been on medical leave in Britain since May 7 and handed over power to his deputy, Yemi Osinbajo, in his absence.
