Braintree Town have announced that manager Hakan Hayrettin has left Cressing Road by mutual consent.
The former Luton coach leaves the Iron following the club's relegation out of the National League.
Hayrettin replaced Jamie Day in September, and led the Iron to the second round of the FA Cup, and to the third round of the FA Trophy, but could not rescue them from relegation.

-Mark Samson (caretaker)
-Danny Cowley (May 2015 to May 2016)
-Jamie Day (May 2016 to Sep 2016)
