Fears were growing last night that the proposed takeover of Leeds United by an un-named Middle Eastern based consortium is on the brink of collapse.Leeds have been in talks with potential purchasers for almost two months but have made no comment on the progress of discussions since announcing on June 26 that an unnamed group were performing due diligence on the accounts at Elland Road.The consortium are believed to be looking for full ownership of Leeds, purchasing all of the 72.85 per cent stake held by existing owner Ken Bates, and it is anticipated that their proposal would see Bates sever his ties with United after seven-and-a-half years as chairman.Sheikh Abdulrahman bin Mubarak Al-Khalifa rumoured to be leading the consortium remains something of a mystery figure with latest reports suggesting he is only acting as adviser to the potential new owners.The Leeds United Supporters Trust(LUST)has issued a statement on the takeover: "The Leeds United Supporters' Trust want to express our frustration and disappointment with the way the takeover of Leeds United is being handled. We believe the time has come for the fans to be told what is happening at their club," "The complete silence from the buyers and the wholly inadequate statements from the club itself have kept Leeds fans in the dark about what will become of their club after this summer. We respect the need for confidentiality and that the legal process needs time. However, we believe that Leeds United's fans should also be respected. "By not responding to calls from the fans for information, the new owners are not beginning this key relationship in a positive way. Our members want to support a transparent and open Leeds United and being kept in the dark about who currently owns or runs their football club does nothing to achieve this."
