Bola Tinubu - the 'godfather' who has been sworn in as Nigeria's president
BBC News, Abuja
Widely credited with reshaping Nigeria's commercial hub Lagos, Mr Tinubu saw off a divided opposition party and a youth-backed third-party candidate in February's election.
Defeated candidates Atiku Abubakar and Peter Obi are challenging his victory in court, alleging the result was manipulated.
Mr Tinubu has rejected the allegation, and has hailed the peaceful transfer of power as "our enduring faith in representative government".
He has replaced Muhammadu Buhari, who has stepped down at the end of his two terms.
Africa's most populous country is facing a troubled economy, widespread insecurity and high inflation.
Many will want Mr Tinubu to hit the ground running when he takes on one of Africa's most daunting jobs.
