Tinubu takes office as Nigeria's president, vows to tackle economic challenges.

Nigeria's new President Bola Tinubu has promised to boost the economy by at least 6% annually, lift barriers to investment, create jobs, and unify the exchange rate while tackling rampant insecurity. Tinubu inherits a struggling economy with record debt, shortages of foreign exchange and fuel, weak naira currency, nearly two-decades-high inflation, skeletal power supplies, and falling oil production. He also promised to reform the security services with more personnel and improved training, equipment, and pay.
