Former chairman speaks out about cancer inside Ibrox
Johnston was chairman of the old club as power switched from Dave Murray to Craig Whyte in a £1 deal just over two years ago.
Last summer he looked on from afar as the club went into administration then liquidation with fears rising that the new club is heading in the same direction.
Charles Green’s sudden appearance and departure has been accompanied by various new figures emerging with a full scale civil war going on in the boardroom due to the vacuum in leadership.
“There is a cancer spreading throughout the club and it’s not going away,” Johnston told The Herald.
“My concern is that until self-serving investors are eliminated then the club can’t go forward. With so many investors – in quotation marks – trying to play an active role in the guidance of Rangers Football Club, I don’t think that is a healthy situation.
“I don’t know the people involved but I really wonder about their agenda. I really wonder in whose best interests are they working.
“A lot of people can say they have the best interests of the club in mind but it is easy to say that.”
Johnston added: “There are people vying for control and influence and they have got to lay down their ambitions and be transparent about finances and investment.
“The board of Rangers – whoever it is and however it is constituted – has to come out and be transparent about the assets and the commitments and what that will mean to investors.
“What has been promised to investors?
“There is a power vacuum and there hasn’t been one in 140 years at Ibrox. Someone has to come out and show guidance.
“Until the supporters can see a line-up of people that they can get behind then they have a dilemma. At some point somebody has to say to the fans we want you to spend money and here is what we’re going to do.”
