Bola Ahmed Tinubu has emerged the winner of a closely fought contest for Nigeria’s presidency. 

• Tinubu, who turned 71 later this month, was governor in Lagos between 1999 and 2007.
• He will become Nigeria’s fifth president since the country returned to democratic rule in 1999, emerging as winner for the country’s top job on his first attempt.
• Tinubu has gone from grass to grace after a rocky start. He left Nigeria for the US to study in Chicago and was sometimes forced to wash dishes to make ends meet, according to the Bola Tinubu library.
