Essex County Cricket Club chairman John Faragher has resigned following an allegation he used racist language in a board meeting in 2017.
Faragher strongly denies the allegation but Essex say they will review why the incident was not fully and independently investigated at the time.
Essex chief executive John Stephenson, said: “There is no place for discrimination of any kind at Essex County Cricket Club.”
An Essex statement said: “John Faragher has resigned with immediate effect as Chair of Essex County Cricket Club following a historic allegation of racist language used by him at a Board Meeting in 2017.
“Faragher stepped down following a meeting of the Board on Thursday evening.
“Essex County Cricket Club does not tolerate discrimination of any kind and will immediately consider further steps the club must take.”
Stephenson, who took over as Essex chief executive in October and said he first found out about the alleged incident this week, added: “This is a proud club with a zero-tolerance policy towards racism and any form of discrimination and I will not hesitate to uphold those principles and drive out any form of discrimination that is uncovered.
“I was made aware of this single allegation on Thursday having joined the club four weeks ago.
“We are committed to working with the England and Wales Cricket Board to eradicate discrimination from the game. This is an important first step, but the club must now act further.
“Our internal reporting mechanisms will be reviewed to ensure that matters such as this are dealt with appropriately and immediately. I intend for those next actions to be communicated as soon as possible.”
