Explaining his reasons for launching a bid to save the club, Mr McColl added: "I think there is real concern about the Charles Green bid and what might happen. A number of people have been approached by him. They feel uncomfortable about the way it is going.
"We wouldn't have come out with this if we had been comfortable, if the deal was going through, the club was being saved and everything was going to be hunky-dory. But I think there is real concern about this being a re-run of what has happened before.
"There is a real concern. The focus here is to make sure this is stabilised and safe, that is all. Rangers Football Club is far too important for Scotland, Scottish football, and Glasgow to be messed up again.
"Our bid is because the group that is involved want to make sure that it is in good hands, in safe hands.
"A number of the individuals in our group have great concerns because of their interactions with Green. The way it is going, there is not enough transparency. There is just worry, with all the club has been through. The group here has decided that something had to be done to fix this – to try to recover the situation with the club.
