INEC was an independent body but not anymore. After the government bought them in the last election when they said the results of the election when everyone was still sleeping. As of now, the people have lost complete trust in INEC, that I won't blame them. What the citizens witnessed is enough to lose that trust.
This just shows that INEC is independent on paper and not truly an independent body. For the most part, they are not being hold accountable for any wrong doings. Even the government sef are above the law. The body just lack transparency and that supposed to be the core backbone of the body INEC.
Since the existence of Nigeria INEC have never operated in a neutral ground and saying they stopped being independent in the last concluded election is a complete lie because I have never seen Nigeria INEC make any fair judgement in Nigeria elections.
If you say this manipulations started in the last concluded election, what can you say happened when Muhammad Buhari won goodluck Jonathan, then it was very difficult for the INEC chairman to announce the winner because even him was confused on the level of manipulation that happened in that years election result.
