Nottingham Forest owner Evangelos Marinakis has removed himself from control of the club by officially withdrawing his position at Companies House.
The Greek billionaire still owns Forest, but he has put all of his club shares into a blind trust so that he no longer has control or influence over the day-to-day running of the club.
Sky Sports News has been told this could be a temporary measure because of a possible conflict of interest with another club in Marinakis' stable, Olympiakos.
UEFA rules dictate that no individual is allowed to control two clubs that are competing in the same competition, and Forest and Olympiakos are both pushing for places in next season's Champions League.
Olympiakos are 13 points clear at the top of the Greek Super League, while Forest would go third in the Premier League if they win their game in hand against Brentford on Thursday.
