The Attorney General has said he has no knowledge of any further ministerial correspondence in relation to the Naughton affair.
Michael McDowell's comments come as the Dail prepares to debate the events which led to Bobby Molloy's resignation.
Labour has claimed that there are two further letters which have not been published. However, Mr McDowell said he is unaware exactly what the Labour party is seeking.
He added that if they wish to see the letter originally written by the sister of convicted rapist Patrick Naughton to Judge Michael O'Sullivan, it is unlikely it would be published because of legal complexities.
