Why has Davuto?lu stolen Hakan Fidan from Erdo?an?

Turkish President Recep Tayyip Erdo?an has thrown a new curveball by explicitly expressing his opposition to the resignation of Hakan Fidan, the head of the National Intelligence Organization (M?T), from his post to run for parliament. Since news of Fidan?s resignation broke, Erdo?an has twice stated that he wanted Fidan to remain in his post, saying the M?T is not an ordinary institution and reiterating his confidence in the spy chief by describing him as ?his secret keeper.? 
 
President Erdo?an has said the same thing to Prime Minister Ahmet Davuto?lu, expressing his opposition to Fidan?s departure at a moment when there are critical issues facing him and the government: The peace process and the fight against the ?parallel structure.?
 
?Whoever comes to the post is very important, because what we have experienced and what we have suffered in the struggle against the parallel structure [of followers of U.S.-based Islamic scholar Fethullah Gülen] is self-evident. In such an environment, I don?t find such a situation to be appropriate,? Erdo?an said bluntly.
 
Erdo?an, who always likes to speak as openly as possible, did not hide his frustration with the resignation. ?I always say that even if I?m left on my own I will continue this struggle to the end, against the parallel structure and those like it,? he added.

So what could be the reason for the Davuto?lu-Fidan duo to challenge their ultimate leader and not listen to him? Another question: Why did Fidan opt to become a deputy, even though this is not a prerequisite for taking a ministerial post?
 
The reason is very simple:...
