Save the Children has declined to comment on reports that Brendan Cox, its director of policy and advocacy, left the charity amid complaints about "inappropriate behaviour" towards women.
The Mail on Sunday newspaper reported yesterday that some staff at the charity complained there had not been a proper investigation of the allegations.
Cox, who quit in September after four years in the role, denied the claims made against him. "The rumours are untrue," the paper quotes him as saying.
Asked about the allegations, a Save the Children spokeswoman said: "We never comment in any circumstances on individual members of staff, past or present."
This news comes after Justin Forsyth, the charity’s chief executive, announced that he would stand down in February after five years in the role.
The two events were unconnected, according to The Mail on Sunday.
