The UK government is seeking clarification on circumstances under which the Nigerian government extradited Nnamdi Kanu, a dual national of both countries, over crimes related to his secessionist movement.
Mr Kanu, who the Nigerian government labelled as a fugitive for being the leader of the proscribed organisation Indigenous People of Biafra (IPOB), was brought to Court in Nigeria on Wednesday after officials claimed they had arrested him in London, UK.
