Barely 24 hours after his inauguration as President and Commander-in-Chief of Nigeria, it appears President Muhammadu Buhari may have broken a campaign promise to scrap the office of the First Lady. An official portrait of the wife of President Buhari with complements of the national flag of the Federal Republic of Nigeria to match her new office has been released by the Presidency.

Personally, I find nothing wrong with this portrait. Even if the office of the first lady is scraped, she will still be invited to functions and of-course, her picture would be needed to print banners.
