The Chairman of the Independent National Electoral Commission (INEC) Prof. Mahmood Yakubu has announced the collation of the Presidential and National Assembly results will start on Sunday.
He stated this on Saturday while giving updates on the voting process nationwide.
Yabuku said the Bi-modal Voter Accreditation System (BVAS) worked perfectly well in most of the states across the federation, but the body experienced challenges in some parts of the country.
Yakubu said the challenge experienced was the inability of the Commission to open the polling units by 8:30 am as agreed in a number of polling units.
