SHELTERBOX founder Tom Henderson has appealed after being replaced as its chief executive over a "combination of issues".
The unanimous decision was taken by the charity's board of trustees.
In a statement, ShelterBox told the West Briton the move was due to a "combination of issues" but would not elaborate.
Mr Henderson, still mourning the loss of his wife, Jane, who died earlier this month, said: "I can't comment at this stage."
Mr Henderson was appointed the OBE two years ago because of his work in founding the humanitarian aid charity, which remains based in Helston.
Rumours were rife locally at the weekend that Mr Henderson, a former Royal Navy search and rescue diver, had been ousted from the post he has held with the charity which he founded in 1999.
ShelterBox issued a statement to the West Briton on Monday.
A spokesman said: "I can confirm that Tom Henderson is no longer chief executive officer of ShelterBox.
"The decision was due to a combination of issues."
She also said it had been a unanimous decision by the charity's board of trustees. There was an appeal process taking place and she added: "We don't want to prejudice any outcome."
She assured the public that the charity's work would continue "unabated" to provide aid to victims of disasters.
She added: "Tom Henderson will always be the founder of ShelterBox," and the charity was "immensely proud" of his work.
Mr Henderson's wife died at the beginning on this month and was described by friends as the epitome "of the supportive wife and soul-mate to her husband".
ShelterBox remains a popular cause in and around Helston and Cornwall and has been adopted by the Rotary Club worldwide. It held an open day at its Water-ma-Trout industrial estate base on Saturday, drawing nearly 300 people and raising £11,000 for disaster relief operations.
Mr Henderson came up with the idea to provide boxes containing a tent and other items to help provide shelter for up to ten people.
It spread worldwide and each year thousands of pounds are raised to buy the boxes which have been used in disasters all over the globe.
