Rangers director Chris Graham was forced to resign from the board yesterday, just three days after being appointed.

The Rangers Supporters Trust spokesman was only handed his role on Tuesday but was ousted amid allegations that he tweeted a photo of the prophet Mohammed engaged in a sex act with Star Wars character Jar Jar Binks.

The image was posted from Graham’s account just hours after the Charlie Hebdo attack in Paris in January. Muslim leaders in Glasgow had demanded the club take action against Graham, while Police Scotland have confirmed they are now investigating the matter.

In a statement made to the stock exchange shortly after 2.30pm yesterday, the club announced: “Chris Graham has tendered his resignation as a director of Rangers. This has been accepted by the board.”

Graham’s short-lived directorship is a major embarrassment for Dave King’s new regime just a week after they snatched power at last Friday’s general meeting.

King — who has not yet taken up his seat on the board while he sets about proving to the football and City authorities that he is fit and proper — had promised to ensure the club’s supporters were represented at director level after they backed his boardroom coup.

Graham was nominated on behalf of the RST, while Rangers First member James Blair has been handed the role of club secretary.

Speaking on Tuesday, interim chairman Paul Murray said: “Chris and James have been appointed in accordance with the board’s commitment to meaningful fan representation and in order that they can use their abilities to contribute to the company.”

Meanwhile, the Scottish Football Association  announced that Rangers’ appearance before a judicial panel disciplinary hearing into Mike Ashley’s Ibrox involvement, originally scheduled for Monday, has been postponed “at the request of the club” until Thursday April 16.
