Lardi,
I think we now have an explanation of why Meire and Joyce left so quickly, Meire was RD's Lawyer during his DD and Joyce is/was the current Finance Director of the Club and obviously neither of them explained the importance of preferential nature of the former Directors/Murray's debt ..... RD was obviously of the opinion that either he could (a) just 'pass on' the debt obligation or (b) subordinate this ex-directors debt below his own. He has now been told that the former directors debt is preferential and must be paid out first (also it now seems payable with a change in ownership not just promotion to PL?) which I guess has made him angry. Exit Meire and Joyce from our story.
With his main two reasons for owning Charlton now gone -
1) Owning a English Football Club for his network
2) Giving Meire a job she obviously enjoyed
We have to ask ourselves what is the reason for him to continue to cover the monthly losses? As far as I can see the answer to this is that there is no reason to continue ownership and the sooner he accepts the real world situation and sells at a loss the better for him.
