The presidency has come hard on Mr Peter Obi of the Labour Party over his pledge to do a single term if elected president of Nigeria in 2027.
There has been controversy over Obi’s commitment to do only one tenure and then hand over a Northerner.
Governor of Anambra State, Chukwuma Soludo has gone as far as saying anyone making such a pledge needs psychiatric examination.
But Obi re-echoed his pledge, describing it as a vow and a bond.
The presidency has now reacted, through President Bola Tinubu's Special Adviser on Information and Strategy, Bayo Onanuga.
He described the former Labour Party's presidential candidate, Obi, as a liar.
Onanuga said Obi was neither Mandela, Abraham Lincoln, nor John Kennedy of the United States.
Onanuga posted on X: "You're neither a Mandela nor a Lincoln or a Kennedy. You sound as if you have never held an elected office before. You sought re-election as Anambra Governor in 2010, and narrowly won courtesy of a divided opposition. Why didn't you walk away after only one term in office?
"Meanwhile after serving two terms, did Anambra look like a state that has been transformed? If you couldn't transform a small Anambra after 8 years, is there a guarantee that you'll do anything significant under 4 years as President of a complex and complicated Nigeria?
"You talk about keeping your promises or your vow being your bond, but you and I know that's not true. You have broken previous promises and usually lie with reckless abandon, sometimes needlessly.
"For example, you said you won't leave APGA but you left (the reason for your exit is immaterial because if we're to make allowance for excuses, you'll definitely have an excuse to break your one-term vow).
"You talk about trust, but how do you expect people to trust someone who can't keep a simple promise not to leave a political party?"
