Loyalists of the All Progressives Congress (APC) presidential aspirant, Bola Tinubu have warned the party against bias.
On Tuesday, scores of them protested at the International Conference Center (ICC), Abuja.
They accused the APC leadership of replacing the names of a number of delegates.
Prominent among the supporters was Segun Dada, who sought to become the national youth leader at the March convention.
The delegates substituted are believed to be party members backing the ambition of the former Lagos Governor.
Tinubu faces a major battle as his opponents within the APC are reportedly working for a “younger aspirant”.
The presidential primary election at Eagle Square in Abuja is underway with the accreditation of delegates.
