Any truth in what Dr Junaid Mohammed is alleged to have said?

Mamman Daura is a powerful member of President Buhari’s kitchen cabinet. In fact, he is considered by most as the de facto Vice President of Nigeria.

Most critical decisions – such as the choice of Ministers and other important appointments - have been credited to him. He even lives in Aso Rock.

Mamman Daura is President Buhari’s nephew. His father is the elder brother of Buhari.

Mamman Daura has a son. His name is Kabir Daura. He is President Buhari’s Personal Assistant.

Abba Kyari is the Chief of Staff to the President of the Federal Republic of Nigeria. He also happens to be the foster child of - Yes. You guessed it - Mamman Daura.

Then there is Hadi Sirika.
Hadi Sirika is the Minister of State for Aviation. He is the son of Buhari's elder sister.

Hadi Sirika has an elder sister – a niece of Buhari. Her name is Amina Zakari.
Amina Zakari was INEC acting Chairman last year.

Then there is Aisha Abubakar. She wasn’t even a member of the APC. But all that didn’t matter. But today, she is the Minister of State for Trade, Industry and Investment. Her mother is Buhari’s sister.

So, friends, there you have it. And, thanks for your time.

I guess we can all now go back to our various lives and continue pretending not to notice how our national affair has become one man's family affair."
