The vice president of the Jersey Animals' Shelter (JSPCA) has resigned, saying he has grave doubts about the way the charity is being run.
Noel Martin's resignation follows the resignation of president Jonathan Morley-Kirk last week.
An investigation into how the JSPCA is run was carried out last year following allegations of financial discrepancies.
A former volunteer also said there was a "climate of fear" among staff.
Jersey Financial Services Commission director Roger Bignell, who carried out a four-month investigation, said there had been breaches of the charity's constitution and problems with the way finances were managed and accounted for.
He urged the charity to carry out a full independent review of staffing and introduce better minute taking at meetings and better account keeping.
Former States vet Mr Martin said: "I sincerely believe that the way forward for the JSPCA is not the way the majority of committee members wish to go. I felt that I was standing alone.
"I am not resigning for ill health, personal reasons, personal conflict or differences with personalities but simply because I do have grave doubts that unless there are significant changes the situation will stay very much the same and the JSPCA will not be in tune with the 21st century."
Mr Morley-Kirk said he was stepping down because of "changes in his private life".
Nick Blampied, who has been appointed as president, said the JSPCA will be changing the way it manages its finances.
