Rangers directors Andrew Ellis and Dave King have called for the resignation of Ibrox owner Craig Whyte.
London property developer Ellis and King, a South Africa-based businessman, have contacted the club's administrators Duff and Phelps with their demand.
A statement released through Press Association Sport read: "We can confirm that as directors of Rangers, we (Andrew Ellis and Dave King) want Craig Whyte to step down with immediate effect in order to safeguard the future of the club.
"He has been found not to be a fit and proper person to be an official at a football club by the Scottish Football Association.
"Moreover, he has not done the right thing in the past for Rangers and we believe that he will not do the right thing for the club in the future.
"It is abundantly clear that Craig has misled the Rangers board and the fans but by walking away immediately we believe and hope it will make the sale of the club easier."
Whyte has repeatedly denied any wrongdoing since taking over Rangers last May and since the club was plunged into administration on February 14.
A spokesman for Duff and Phelps, who are in discussions with three parties over a takeover of Rangers, told the Daily Record: "The powers of all directors are effectively removed when a company goes into administration - unless the administrators decide otherwise.
"We will consider the request of Messrs Ellis and King and, if necessary, will review the position of any or all directors should it be a material issue for the preferred bidder, once that party is selected."
