Liverpool have announced that Tom Hicks Jr, son of co-owner Tom Hicks, has resigned as a director of both the club and its parent company, Kop Holdings.
The American, son of co-owner Tom Hicks, became embroiled in controversy on Sunday when it emerged he had responded abusively when one supporter contacted him directly about the state of the club and their finances.
Having initially called the fan an "idiot", Hicks Jr reportedly then sent a second e-mail saying: "Blow me f*** face. Go to Hell. I'm sick of you."
Hicks Jr subsequently apologised but he has now quit the club.
The Spirit of Shankly fans' group, who are committed to the removal of American co-owners Hicks Sr and George Gillett, had called for Hicks Jr to resign.
However, with his father as co-owner it appeared there would be little pressure from the top to do so.
Hicks Jr was seen as a key player on Anfield's finely-balanced board - comprised of Hicks and his father, Gillett and his son Foster and managing director Christian Purslow.
However, at the same time Liverpool announced his departure they revealed a re-structuring of the boardroom of both the club and Kop Holdings.
Casey Coffman, executive vice-president of Hicks Holdings, is the man brought in to replace Hicks Jr while Liverpool's chief financial officer Philip Nash and the club's commercial director Ian Ayre are have also both been elected to both companies.
