In a statement released by his Senior Special Assistant on Media and Publicity, Mallam Garba Shehu, Buhari said such rumours were unfounded and mischievous.
He insisted that he was in constant communication with Tinubu before, during and after the Ondo governorship election last weekend.
Buhari hailed Tinubu as a priceless political asset to the party and said the presidency and APC leadership was not working to destroy the former Governor of Lagos State.
The statement read: “President Buhari commended Tinubu’s spirit of comradeship in promptly congratulating Rotimi Akeredolu who was elected Governor.
“The President also noted that at a time his administration is preoccupied with governance issues, rumours of divisions and alleged scheming within the party are counterproductive to internal unity and cohesion in APC.”
He also appealed to APC members and supporters to ignore rumours that could harm the ruling party’s unity.
