A pan-Yoruba group, Yoruba Professionals Foundation (YPF), has slammed northern leaders critical of relocation of the headquarters of the Federal Airports Authority of Nigeria (FAAN) and the Department of Banking Supervision of the Central Bank of Nigeria (CBN) to Lagos State. The group in a statement issued on Monday by its Director of Administration, Oladapo Kayode, described the criticisms as very unfortunate, dishonourable, outrageous, and irresponsible.
