We wouldn't be in this position if BG hadn't accepted a bid from an anonymous consortium, with a letter from a solicitor. There was always a chance that a consortium, who wished to remain anonymous, was doing so because at least one of their members was going to be unacceptable to the FL. He should have insisted on names at that point or disallowed the bid.
How much money was promised in that solicitor's letter (aren't we talking about £5 million)? Where is it now, and, if it's not there, can the solicitor be sued?
