While speaking at the presidential villa in Abuja on Monday, wife of the president, Aisha Buhari, stated that the leader of the Indigenous People of Biafra (IPOB), Nnamdi Kanu, gained grounds while her husband was receiving medical attention in London.
According to TheCable, the President’s wife said the absence of Buhari who spent over 100 days treating an undisclosed ailment in the UK, during which Nnamdi Kanu addressed thousands of his supporters, vowing to ensure the realisation of Biafra, created a setback for the federal government.

She said; “As a result of the president spending several months outside Nigeria, a 40-year-old man who was still living in his father’s house created a state out of a state and that is a major set back for the country and the health sector did not benefit.”

It looks like he surely did. Things changed when the president came back.
