Creag Robertson has become the latest high-profile figure to quit Ibrox after resigning from his position as director of football operations.

The Rangers Review understands that Robertson will leave the club after just 18 months in the role. It is believed that Robertson will depart before the end of the year to pursue new opportunities away from Ibrox.

Robertson was promoted as part of the major reshuffle that former chairman John Bennett conducted last summer. James Bisgrove lasted just one campaign as chief executive officer before taking up a post in Saudi Arabia, while Bennett stepped down from the board last month due to health concerns.

John Gilligan was appointed as interim chairman to steady the club at boardroom level and oversee the search for a new CEO. Now Robertson's position at Ibrox will also need to be filled at a time when Rangers remain in the market for a head of academy to replace Zeb Jacobs.

Gilligan spoke to the media for the first time last month as he addressed a range of issues amid comments from Dave King calling for an EGM to be held as he seeks to return to the Ibrox board. Gilligan now has another item on his to-do list.

"I will stay on as long as required," Gilligan said. "The main priority is to get a chief executive. We are working on that right away. I can stay on indefinitely, I am expecting a few months and a chairman to come in too.

"Recruitment in any walk of life is of the moment. The person needs to be multi-faceted and good at everything. He needs to be an assertive character and we are looking much more to provide for the CEO via the chairman. And also for the CEO to have a lot of power day to day and the chairman to be slightly behind that.

"There is a plan and I am here to bring stability to the enforcement of that plan. We have been distracted terribly by having to play at Hampden for a few months and a lot of people forget that the original objective here was to create a great facility for our disable supporters. It wasn’t a renovation, it wasn’t a reconstruction. 

"Unfortunately the timing was wrong, we got that part of it wrong, and we had to go to Hampden. But everything is in place, the manager is in place and we are ready to keep going. We see some fruits for our labour now with some of the young players coming through and I am here to bring stability and help find a CEO."
