Tom Henderson's association with the charity he founded ended in an email which demanded he stay away from ShelterBox premises.
An email to Mr Henderson from chairman of trustees Ian Munday was titled "Withdrawal of offer of presidential role". It was sent at 9.30pm on August 2.
"I must inform you that, on legal advice, the offer is formally revoked with immediate effect," it read. "Following your dismissal as CEO (chief executive officer), the board requires you to return all company property forthwith. This includes keys to the charity's properties, your credit card, the car and car keys, the laptop, the mobile phone and all file, papers and records belonging to the organisation which you recently removed from your previous office including all copies in electronic form or otherwise."
It went on: "You are to no longer attend at any of the ShelterBox premises. Further you are to desist immediately from holding yourself out as an employee, consultant or any form of representative of ShelterBox."
It concluded: "Despite the circumstances the board do acknowledge all the work you have done to build the charity and we shall endeavour to continue that work to preserve your legacy."
Later that night staff were told, again by email, that Mr Henderson had "not accepted" the position of president.
In another email on the night of August 2, Mr Munday wrote to international affiliates saying the board had been "working to resolve a major issue concerning the breach of a key policy by CEO Tom Henderson".
"This risk posed a significant risk to the charity and there is a legal obligation to report this to our regulator the Charity Commission. Following an independent investigation and although they do not believe the law to have been broken, the trustees have taken the decision that it is no longer appropriate for Tom to retain the position of CEO or any other executive post."
The above details are from the leaked documents, which are not a complete record.
