The South Africa-based multi-millionaire businessman has offered a financial olive branch to the Ibrox board. But he has urged the Ibrox powerbrokers to offer Paul Murray a place on the beleaguered board as a compromise after months of bitter public mudslinging.
King's comments came as hundreds of fans were expected to converge on Ibrox this morning for the make-or-break summit.
He said: "Whoever has the power, I'm happy to be one of the primary providers of any funding they require. It's up to them to refuse it, but quite frankly I don't see anybody else wanting to put money into the club at this moment in time.
"But am I still keen to get involved? Absolutely, absolutely. More than keen.
"The actual role would depend [on future discussions] but certainly to help with attracting investment.
"If there is still a chairman there then there's still a chairman and that's fine. We will see how it goes."
Fans' hero King made a whistle-stop visit to Scotland last month to try to broker a peace deal between the various factions at Ibrox.
And he was prepared to take up the vacant role of chairman.
Since then, Norman Crighton has joined the board, Graham Wallace has been appointed as chief executive and David Somer was named chairman.
But King reckons Murray's appointment to the board would unite a split fanbase - and help end the civil war that has torn the club apart.
With the current directors tipped to retain their places today in the face of bitter fan opposition, the Castlemilk-born tycoon urged them to hold out an olive branch to the leader of the Blue Knights.
The former Ibrox director said. "It would help them, if their position is secure and they know it to be secure, to at least get Paul on board.
"I would strongly urge the incumbents to do that. That would be a good gesture and the right thing for them to do. It would help them to get someone of Paul's experience on the board.
"He's a good Rangers man and a good businessman. He knows what it's about and is interested in the club for all the right reasons. It makes good business sense.
"We know his heart is in the right place and he's a smart guy. It would send the right signal to the supporters.
"It would be a very sensible, pragmatic and practical gesture from the board. That might help the fans because they would have a high level of confidence in Paul's attitude and experience."
