George Cook has resigned as chief executive of sector services organisation Charity Logistics.
Cook has left the Kent-based charity to work for the Charity Disaster Recovery Network. A former project of Charity Logistics, the network offers emergency office facilities for charities at 30 sites nationwide.
But the future of Charity Logistics remains unclear, and a statement is expected from the board of trustees next week.
The Charity Disaster Recovery Network will operate initially from Charity Logistics' main office in Maidstone until a new location can be found.
"I hope to continue as a consultant to Charity Logistics until 31 December," said Cook. "I also intend to apply to be a trustee for 2006."
