GREIG Box Turnbull will leave his role as Oxford United's managing director at the end of this season.
The former Daily Mirror journalist was appointed 12 months ago after chief executive Mark Ashton left the club in December 2015.
Box Turnbull took on the day-to-day running of the club's business operations and joined the board under chairman Darryl Eales.
He will retain his position as a trustee of the Oxford United Community Trust.
Eales said: "Greig has done an excellent job for the football club and I am grateful for his significant contribution.
"We have firmly established the club in League One, taking it to the next level both on and off the pitch and Greig has played a big part in this progression.
"Greig has become a good friend and I am delighted that he is staying on as a trustee of the charity.
"We all wish him well for the future and seeing him around the club on a regular basis."
Box Turnbull added: "It's been an honour and a privilege to represent the club I love this season.
"Much has been achieved in many areas of the club over the past 12 months, especially building a more professional infrastructure able to cope with the progression of the club on the pitch.
"I will be leaving the club in a stronger place and in an excellent position to continue the amazing progress over the past couple of years.
"I have a great relationship with Darryl and Michael (Appleton, head coach) and wish them and all of the staff every success in the future.
"I'm looking forward to continuing as a trustee of the Community Trust and building on the progress it has made this season.”
