The Blues' co-owner and chief executive officer respectively, who have been at St Andrews for the last sixteen years, have decided to quit the club once the proposed takeover is completed in what is expected to be a matter of weeks. "I have worked tirelessly on bringing in the managers and players that have taken the club into the Premier League, as well as being involved on a daily basis in all aspects of the club's business. We have given 16 years of our life to Birmingham and are proud of what we have achieved. "I intend to remain in football, so following the takeover I will be looking for a new challenge where my experience, my success and sound business acumen will make a difference. "Finally, I wish the supporters well and hope that the new owners will be able to build upon the firm foundations we have laid for them." "Grandtop have asked me to retain my position as CEO, but I honestly feel they must be allowed to stamp their own mark on the club and I believe that this is best done without the current board looking over their shoulder. "I leave with very fond memories of the past 16 years; I arrived with David Sullivan in 1993 and I want to leave with him. Whatever he does in the future, you can rest assured I'll be standing by his side. "We have been extremely successful at running the club together, setting the business standards that, if continued, will ensure the long term future and prosperity of this great club. "David Gold has confirmed that he is remaining in his position as chairman so that he can continue doing the fantastic PR job he has done for us over the past 10 years for Grandtop."
Co-owner David Gold is expected to remain in his role as chairman of the club.
A statement on the club's official website has outlined the couple's intentions.
David Sullivan told bcfc.com: "Karren and I have worked extremely hard to make Birmingham a bigger and better club over the past 16 years.
Karren Brady has said: "It was a hard decision for me to make to leave the club after so long but with the new change in ownership I feel the time will be right for me to move on and pursue my other ventures.
