Independent senator Frances Black has said she feels it is unlikely she will be running as a candidate in the Presidential election.
Speaking to RTÉ News, she said that she had not been contacted by any political parties and felt, at this stage, the door was closing.
Senator Black did not completely rule out standing, but said she has a lot of work still to do in the Oireachtas.
In political terms, Senator Black is most closely associated with the Occupied Territories Bill - she first tabled her proposed legislation on the topic back in 2018.
She has continued to campaign on the issue and held meetings with Tánaiste Simon Harris on the Government bill, which was approved by Cabinet.

In March, Senator Black disclosed that she had been approached by a number of parties about running in the presidential election and indicated she would be open to the proposal.
The fact that no party followed up on the idea and engaged in talks appears to have led her to conclude today that she is not going to run.
Fine Gael is set to choose its presidential candidate next month; Fianna Fáil will only decide on the process of selection in July; while Sinn Féin is consulting its membership on the issue.
The Labour Party, Social Democrats, Greens, Independent Ireland, Aontú, and Independents have yet to forge an alliance, or alliances, to meet the threshold of having the backing of either 20 Oireachtas members, or the backing of four Local Authorities, in order to run a candidate.
