Former President Goodluck Jonathan has revealed how the conduct of the former U.S. president Barack Obama, cost him his re-election bid for a second term in office.

In his book My Transition Hour, Jonathan stated that the conduct of the ex-US president was overbearing and condescending in his message to Nigerians ahead of the 2015 general election.

The ex-Nigerian president also disclosed that Mr Obama displayed an unusual level of bias during the 2015 elections, issuing a video appeal to Nigerians which all but advised them on which candidate to give their mandate.

“On March 23, 2015, President Obama himself took the unusual step of releasing a video message directly to Nigerians all but telling them how to vote,” Mr Jonathan said in his new book, ‘My Transition Hours’, which launches Tuesday.

“In that video, Obama urged Nigerians to open the ‘next chapter’ by their votes. Those who understood subliminal language deciphered that he was prodding the electorate to vote for the opposition to form a new government.”

Jonathan in the new book said the message in Obama’s video message “was so condescending, it was as if Nigerians did not know what to do and needed an Obama to direct them.”

He also took a swipe at former U.S. Secretary of State, John Kerry, saying the top diplomat was nonchalant in his attitude towards his government despite all efforts to make him understand that the decision to postpone election was in the overall interest of Nigeria.

“How can the U.S. Secretary of State know what is more important for Nigeria than Nigeria’s own government?” he asks. “How could they have expected us to conduct elections when Boko Haram controlled part of the North-East and were killing and maiming Nigerians?

“Not even the assurance of the sanctity of May 29, 2015 handover date could calm them down. In Nigeria, the Constitution is very clear: No President can extend his tenure by one day.”
