Buhari was believed to be seeking Jonathan’s help to bring the crisis to an end and spare the nation’s economy of unwarranted damage.
In an apparent move to prepare the ground for this meeting, the president had in recent days been speaking glowingly about the former president whose activities in office have been the subject of investigations by the Economic and Financial Crimes Commission (EFCC).
Buhari had engaged in praising Jonathan over the defeat concession phone call the latter made to him before the final tally of the 2015 presidential election result was known.
President Buhari also, on Friday, hosted former President Olusegun Obasanjo to a secret meeting at the Presidential Villa, Abuja.
The meeting, which took place inside the president’s office, lasted for about 30 minutes.
