After spending more than a year-and-a-half in a Nigerian jail without trial on treason charges, Nnamdi Kanu is now free on bail. The BBC’s Stephanie Hegarty explains who Nwannekaenyi “Nnamdi” Kanu is and why he attracts so much controversy
Nnamdi Kanu founded the Indigenous People Of Biafra (Ipob) in 2014.
The movement wants a group of states in south-east Nigeria, made up mainly of people from the Igbo ethnic group, to break away and form the independent nation of Biafra.
The plan is not new. In 1967 Igbo leaders declared a Biafran state, but after a brutal civil war, which led to the deaths of up to a million people, the secessionist rebellion was defeated.
But the idea of separatism has bubbled away since then and Mr Kanu is the latest in a line of Biafran activists taking up the cause.
