The Trust were never going to buy the club. They know that, and Birch knows that.
For them, it's either:
Plan A½ - hand over the money they've personally borrowed to Chainrai in exchange for a share of the debt, or
Plan B - use their million or so to establish a re-formed club after liquidation
Recent reports about firing Birch point to the general realisation that it's Plan B he's working on, and some of the influential creditors don't like that.
