"We're delighted to welcome James back to Killie," director Billy Bowie said.

"James's experience for the role is second to none and we're all looking forward to working with him going forward."

"I am thrilled to be coming back to the club," he said before taking up the post on Monday.

"With the experience I've gained in the last five years in various roles within the industry, I feel that this is the right opportunity for me to implement my ideas.

"The club and supporters have always been so welcoming, and I am looking forward to working with the board, Angelo Alessio and his staff, and the fans to continue to build the strongest team we can."
