Former Rangers boss Walter Smith admits he should never have joined Charles Green's Ibrox board.
And the nine-titles-in-a-row manager also confessed he should have walked away much sooner before he did finally quit in August 2013.
The 66-year-old returned to the club in November 2012 after being appointed a non-executive director by then chief executive Green - and he was then handed the chairmanship six months later.
But he soon resigned as he accused the Yorkshireman and former directors Brian Stockbridge and Bryan Smart of creating a "highly dysfunctional environment" inside the Ibrox boardroom.
Smith said: "Everybody talks about it being chaotic. Everybody can make up their minds about what happened. It was chaotic enough for me to resign.
"For my own embarrassment I maybe held on a bit too long. I should have resigned long before I did.
"But that happens. It was an error on my own part to get involved."
He added: "Would I have done anything differently? Yeah, I probably wouldn't have joined the board at all. Why? Just the way everything turned out.
"I felt at the time that if I could help the club in any way with the circumstances it was in, it was the right time to do so."
