Nigeria 2019 presidential election postponed breaking news
I'm not aware of any breaking news about the 2019 Nigerian presidential election being postponed. The 2019 Nigerian presidential election was held on February 23, 2019, and the results were announced on February 27, 2019. Muhammadu Buhari of the All Progressives Congress (APC) won the election, defeating his main opponent, Atiku Abubakar of the Peoples Democratic Party (PDP).
It's possible that you may be thinking of a different election or a different year. If you could provide more information or clarify what you're referring to, I'd be happy to try and help you find the information you're looking for.
It's also worth noting that the Independent National Electoral Commission (INEC) is responsible for conducting elections in Nigeria, and they would be the ones to announce any changes or postponements to an election. If there were any changes to the 2019 presidential election, INEC would have made an official announcement.
