The Northern leaders were already seated at the venue before they were informed of the postponement.
Osinbajo's meeting with the Northern traditional rulers is following his consultations with Governors and stakeholders from the South-East.
According to political observers, the consultations are aimed at dousing the tension emanating from the eviction notice to Igbos.
A group of Northern youths had earlier issued a statement asking Igbos to leave the North.
Reports say the Northern leaders were already seated at the venue before they were informed of the postponement.
According to Daily Post, Osinbajo’s spokesman, Laolu Akande said “Tonight, the acting president would be holding iftar dinner with northern traditional rulers and tomorrow continue ongoing consultations with them.
“Both Muslim and Christian traditional rulers from the north would be participating in consultations tomorrow afternoon with the acting president.”
Meanwhile, the Indigenous People of Biafra (IPOB) have described Osinbajo’s meeting with South-East leaders as a waste of time.
