Nigeria's presidency is expected to sign the 2017 budget into law next week.

This is according to the speaker of House of Representatives, Yakubu Dogara.

"The 2017 Appropriations Bill will be signed into law early next week," said Yakubu Dogara on Friday, while speaking at an event to mark two years anniversary of National Assembly since after elections in 2015.

Two presidency sources, who did not want to be named, also told Reuters that the budget would be signed next week.

Nigeria’s record 7.44 trillion-naira budget passed by the Senate on May 11 was bigger than the 7.298 trillion-naira draft spending plan submitted by Buhari in December.

A government official last week said the presidency and lawmakers are still in talks over the spending plan.

Last year's budget, passed in May 2016, was delayed for months due to disagreements between lawmakers and the presidency over spending plans that cut the supply of government money and deepened the economic crisis.

Nigerians are already displeased that the budget was delayed before passage. But now it appears that further delays are inevitable since the budget must be signed by the president.

But the man in charge, President Muhammadu Buhari is not on ground.

He has been on medical leave in Britain since May 7 but his deputy, Yemi Osinbajo, who had been in charge in his absence, has faced criticism over previous plan by him to assent to the appropriation bill.
