When will this end in Cameroon?

There is one major observation many Cameroonians have made. The comportment of ministers during a visual encounter with the media.
Almost every minister works tooth and nail to have Biya's picture at the background.
When a  minister wants to give an interview, they first look round if a gigantic photograph of the president is behind them. 
If they can't spot a picture within the  camera frame, they rush the team to where they can find one. That's loyalty, of course.
I was reading an article on Cameroon-Info.Net when my eyes fell on the Minister of External Relations. Le Jeune Mbella Mbella has a huge photo of Biya behind him, as he holds a document in a seeming reading manner.
And most interestingly, that photo depicts Biya in his very earliest life. The president is young, of course.
Who knows what could happen to a minister who uses Biya's real photo, portraying a face battling with the unseen hands of age? Prison or retirement, who knows.
Eighty-four-year-old Paul Biya commands a lot of respect or fear, depending on how you see it.
He has been in power for over three decades. Most of his men have wound up behind bars, even those who were presumed to be his right-hand puppets.
