FAI vice president John Finnegan has resigned from his post with immediate effect, citing "personal and family reasons".
The Cork man, who has served on the FAI board since 2019 and as vice-president from 2023, will remain as chairperson of the Munster Senior League.
His departure comes a week after the FAI received an anonymous email detailing a series of allegations against named individuals, amounting to a "a wider culture that remains toxic, unaccountable and in many cases unchanged despite past scandals".
While Finnegan has not yet commented on his resignation, his solicitor Brendan O'Sullivan acknowledged that his client had been involved in a disciplinary process with a previous employer in 2013 concerning inappropriate messages he had sent some years earlier.
No criminal proceedings arose from this and the messages at the centre of the dispute did not contain images or photographs.
"He is resigning for personal and family matters. This regrettable incident happened 15 years ago," O'Sullivan told the Irish Independent.
"It was handled at the time and the finding was that inappropriate language was used in messages. John would now like to put this matter behind him."
Prior to his resignation, It had been expected that Finnegan would have been re-elected to another two-year term as vice-president at the upcoming AGM.
In a statement, the FAI wrote: "The Football Association of Ireland confirms that John Finnegan has resigned from his position as vice president of the association with immediate effect, due to personal and family reasons.
"The board has accepted his resignation and thanks him for his service to the association over the past number of years."
