The Constitution does not require that Nigeria's Minsters be exclusively men or women. However in the ministerial list submitted to the Senate president, Bukola Saraki on Thursday, only 3 Nigerian women were nominated as ministers according to multiple reports.

During his campaign, Buhari promised to implement the National Gender Policy, which allocates 35 percent of appointive positions for women.

Former President Goodluck Jonathan brought about an increase in women’s political participation from 10% in 2011 to over 33% in 2013, with the appointment of 13 female Ministers out of 42, and four Special Advisers out of 18.

While we await the names of the outstanding nominees, here are the women to expect in Tuesday's Ministerial List
1. Amina Mohammed
2. Kemi Adeosun
3. Aisha Alhassan

With the level of atrocities committed by women ministers in the last administration maybe PMB has started becoming skeptical about women.

all the major atrocities commited during GEJ's time were masterminded by women.
