Birmingham City owner Carson Yeung has stepped down from all of his positions on the Championship club's board.
Hong Kong businessman Yeung took over at St Andrew's in 2009 and has since presided as president of the club, director of Birmingham City plc and director and chairman of the club's parent company, Birmingham International Holdings Ltd (BIHL).
The 53-year-old, who remains Birmingham's major shareholder, is awaiting the verdict of a money laundering trial in Hong Kong, which is due to take place on February 28.
Yeung denies the charge, but has resigned from his roles in order to concentrate on the court case, with Cheung Sing - another of BIHL's executive directors - named as his successor as chairman of the parent company in an announcement to the Hong Kong Stock Exchange.
"Carson Yeung has taken this decision to focus more time on his on-going court case and to satisfy one of the requirements for the resumption of trading of BIHL shares," club acting chairman Peter Pannu told the club's official website.
"I will endeavour to update supporters further following the forthcoming EGM (Extraordinary General Meeting) in Hong Kong.
"I would like to take this opportunity to thank Carson Yeung for his vision, dedication and generous support for the football club."
