The company of former Rangers chairman Sir David Murray has called for a police inquiry into the leaking of information surrounding the Ibrox club's 'big tax case'.

Oldco Rangers this week won their appeal in principle against a bill from Her Majesty's Revenue and Customs over their use of Employment Benefit Trusts (EBTs) from 2001 to 2010.

Details of the contentious payments to staff and players had emerged on the internet and in a BBC Scotland documentary entitled Rangers - The Men Who Sold The Jerseys, which won a Scottish Bafta on Sunday.

A spokesman from Murray International Holdings (MIH), which was majority shareholders of Rangers until May 2011, said: "In our statement released on 20 November 2012, we highlighted our concerns surrounding the volume of private and confidential information surrounding the EBT case that was made available for public consumption.

"This is particularly the case in relation to the significant quantity of personal financial data contained in the BBC Scotland programme broadcast on Wednesday, 23 May 2012 and set out in correspondence addressed to MIH in advance thereof.

"All individuals have an expectation of privacy in relation to correspondence and matters relating to their financial affairs. It is disgraceful that personal information relating to employees and former employees of MIH and its subsidiaries has been banded about in public in such a casual manner.

"There were only three potential sources of the complete set of documentation utilised in the broadcast and correspondence; being MIH's head office, the First Tier Tax Tribunal and HMRC, together with their respective advisers.

"Importantly, Rangers Football Club PLC did not have access to all of the material covered in the programme and letters.

"MIH's underlying concern is that there may have been criminal offences committed in connection with the provision of this material to the BBC.

"MIH therefore requests a formal independent police inquiry into how this documentation came into the possession of the BBC.

"In this regard, MIH will willingly and openly co-operate with any formal investigation, submitting itself to the same level of inquiry as any third party."

HMRC declined to comment on the matter while BBC Scotland is aware of the statement but has yet to comment.
