Leyton Orient chief executive Matt Porter has been appointed as the League One representative on the board of the Football League.
Porter takes over the role from John Nixon of Carlisle, who stepped down following the club's relegation to League Two, and will represent the 24 clubs in the third tier of English football.
Porter was appointed Leyton Orient chief executive by Barry Hearn in 2006 at the age of 26, becoming the youngest person in the role in English football, and has been at the club for 13 years in total.
Football League chairman Greg Clarke said: "I'm delighted to welcome Matt to the board of the Football League. His successful stewardship of Leyton Orient as well as his experience with other professional sports will prove a great addition to the board. I look forward to working with him."
Porter added: "I am delighted to take up this position and look forward to serving League One to the best of my abilities.
"Further to the club's announcement regarding its potential change of ownership, it has been confirmed that I will continue as a director of the club therefore enabling me to fulfil my duties to the Football League board."
