This is the actual reason why INEC failed to conduct election in its appointed date. Anything that has to do with this race will let you down, the INEC boss should now be watching his back and be extra vigilant.
I personally suggest his sacking or to honourably resign without much rancour.
Nigeria project can never work with these set of people.

Read below please.
"Sequel to the one-week postponement of the elections by the Independent National Electoral Commission (INEC), there have been speculations that Amina Zakari, a national commissioner, is to blame for the logistics delay regarding the electoral process.
In October 2018, INEC re-organised the chairmanship of five of its 15 Standing Committees. As a result, Amina Bala Zakari’s position as Chairman of INEC’s Electoral Operations and Logistics Committee was changed to Health and Welfare Committee.

"A statement by Mallam Muhammed Haruna, a National Commissioner on the re-organisation, read: “Barrister Festus Okoye, Information and Voter Education Committee; Prince Solomon Adedeji Soyebi, Board of the Electoral Institute; Dr Mohammed Mustafa Lecky, Planning, Monitoring and Strategy Committee; Mrs. Amina Bala Zakari, Health and Welfare Committee, and Professor Okechukwu Ibeanu, Electoral Operations and Logistics Committee.”
Note INEC has specifically stated that Logistics and Operations problems were cause of all these embarassments.
