Nigeria has saved over 1 trillion naira ($1.32 billion) in just over two months by scrapping a popular but costly subsidy on petrol and moved to unify its multiple exchange rates, President Bola Tinubu said on Monday. Tinubu is under pressure as prices soar following the country's boldest reforms in decades, which labour unions say have hurt the poor. In a television broadcast, Tinubu defended his decision to scrap the petrol subsidy, which he said benefited a few elites and that the reforms would help boost the economy.
