The Ibrox board were looking to offer new shares without first offering them to existing shareholders, including Sports Direct supremo Mike Ashley, an unpopular figure among a section of the Gers support.
Rangers revealed that Resolution 11, voted on at the club’s annual general meeting in November, was only 0.4 per cent short of the 75 per cent backing it required.
McCoist, who has a 1.25 per cent shareholding in the club, said: “I was one of the 25 per cent who never voted as I was out of the country and a lot more high-profile people at Rangers, people who are close to my heart, also never voted.
“Out of the 75 per cent who voted, 26 per cent voted against resolution 11.
“When Dave King (chairman) and the board were getting voted in (2015) I turned up at Ibrox to vote for that board, strongly against the advice of my lawyer who, believe it or not, wouldn’t talk to me for 10 days.
“But I felt it was the right thing to do.
“What I do with my vote is private so clearly it was leaked by somebody and I have a fair idea who it is.
“It was an attempt to get the fans turned against me which certainly has not been the case as a lot of people saw through it.
“I support the board. Absolutely. I appreciate how difficult a job the board have got and I know the board will be doing their best for Rangers. All I would say is that I just hope they can find investment.
“I remain a supporter of the club and the board and I just hope the board can find the investment to help the next manager.”
