Mr Carey was only appointed as Director of Elections last month.
In a statement released through his solicitors last night, Mr Carey says he doesn't know if allegations about sexual abuse carried in the Irish Independent this week relate to him.
The former Minister says he's deeply upset to have been contacted by journalists following Wednesday's article in the Irish Independent, saying he has no knowledge of the actual complaints allegedly made.
Pat Carey says he absolutely and unconditionally denies any impropriety in this matter or in his 30 years as a teacher, community worker and in public life,
The statement says he was distraught to first learn of these matters on the front page of a national newspaper and is concerned at comments allegedly attributed to Gardai.
He says he doesn't know if the allegations relate to him but given the unfounded speculation he is of his own accord resigning from the Fianna Fáil party and as its director of elections.
Fianna Fáil now says they will make an announcement on his replacement as director of elections in due course.
