Presidential hopeful Seán Kelly has said he is staying in the race for the Áras nomination, pointing out that there is more than a week to go in Fine Gael's selection contest.
Under Fine Gael rules, candidates need to secure 20 nominations within the parliamentary party for the matter to go to a vote.
They also need the support of 25 councillors and five members of the Executive Council.
Former Minister Heather Humphreys has over 40 supporters out of 59 members of the parliamentary party, which would not leave enough nominations for Mr Kelly to make the ballot as things stand presently.
Fianna Fáil, meanwhile, has said it will make its position known next month.
Earlier, Minister for Justice Jim O'Callaghan refused to be drawn on speculation about whether his party would run a candidate in the Presidential Election.
Minister O’Callaghan said the party decided last month that it would make a decision about the presidency at the end of August, start of September.
The justice minister said he would not share his views before meeting colleagues in the parliamentary party.
"I will make my contribution in respect of the issues to the Fianna Fáil Parliamentary Party when we meet, but I am not going to share those views in advance because I think it wouldn’t be fair to the Fianna Fáil Parliamentary Party because it’s the entity that’s to make the decision."
There has been speculation that former taoiseach Bertie Ahern could be nominated by the party, but a spokesperson for the former Fianna Fáil leader said he was not commenting at present.
