Labour Party TDs and Senators have recommended against the party contesting the presidential election.
However, prospective candidate Michael D Higgins has said he will present his case for running tomorrow to the party's National Executive, which has the final say on whether Labour should run a candidate.
If the National Executive accepts the recommendation not to run in the election, party leader Pat Rabbitte has been given the discretion to decide how to respond if the Green Party seeks Labour’s support to nominate Eamon Ryan for the contest.
Meanwhile, the Green Party leader, Trevor Sargent, has called on the Labour Party to back Green TD Eamon Ryan.
In a statement, Mr Sargent said that, following what he called the rejection of Mr Higgins by Labour, swift action was needed to ensure that Mr Ryan could mount a credible campaign.
Earlier today, following months of speculation about whether Mr Higgins would run for the Presidency, he told a meeting of the parliamentary party in Wexford that he was willing to do so.
However, it decided against nominating a Labour candidate, preferring to concentrate instead on forthcoming by-elections and the wider agenda of working towards agreement on an alternative Government.
