Roy Martin QC has been appointed to oversee the independent investigation into former Rangers owner Craig Whyte's claims of links to the club.

The Ibrox board commissioned the probe after Whyte alleged he was involved with the Charles Green consortium's acquisition of Rangers' business and assets last summer.

Whyte was at the helm when the club was forced to call in the administrators in February 2012, before failure to secure an agreement with creditors saw the Glasgow giants consigned to liquidation.

Green has denied any wrongdoing but resigned from his position as chief executive with immediate effect last month amid the "negative publicity" generated by Whyte's claims.

Rangers confirmed at the weekend that commercial director Imran Ahmad had also left the club but declined to comment further on his departure.

A statement from Rangers today read: "Further to previous announcements concerning the investigation by Rangers International Football Club plc ("Rangers") into any connections between Craig Whyte and former and current personnel of Rangers and its subsidiaries, Pinsent Masons, the law firm conducting the investigation, have engaged a Queen's Counsel, Roy Martin QC, to oversee the independent investigation."
