Bristol City have revealed that they have restructured the club's boardroom structure, with several directors taking on new roles.
"The club has gone through a significant period of adjustment and rationalisation over the last few months," chairman Keith Dawe said. "As a result a number of changes have been made at Board level affecting key areas of the business.
"Jon Lansdown moves to become vice -hairman and Doug Harman becomes the club's chief executive with immediate effect. Doug will take overall responsibility for football and our academy, as well as the commercial, financial and operational aspects of our business.
"In addition, Ernie Arathoon is a welcome and recent addition to the Board as a non-executive director."
Bristol City are currently 20th in League One.
