Loyalists of Bola Tinubu, All Progressives Congress (APC) presidential aspirant, have protested against what they say is an attempt to disenfranchise delegates loyal to him.
On Tuesday, some of them protested at the International Conference Center (ICC), Abuja, accusing 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.
The presidential primary election at Eagle Square in Abuja is underway with the accreditation of delegates.
