Labour leader Eamon Gilmore is due to make a statement at 4pm, amid widespread rumours of his impending resignation.
The Tánaiste is facing a motion of no confidence today from within his own party, following an election wipeout which has left the party without any representation in Europe.
Labour also saw their seats on local councils cut dramatically in the elections, with just 7.2% first preference votes, and 50 seats nationwide so far - about half of its previous total.
The motion of no confidence was signed earlier today by TDs Ciara Conway, Dominic Hannigan, Michael McNamara, Ged Nash, Derek Nolan, Aodhan O’Riodain and Arthur Spring, as well as Senator John Gilroy.
This is not just about Eamon Gilmore but his style&culture of leadership. I am tired of being bullied by his henchmen, censored&isolated— John Whelan (@SenJohnWhelan) May 26, 2014
Gilmore's statement to the media will take place at the Department of Foreign Affairs and Trade at Iveagh House at 4pm.
Earlier, Labour's deputy leader Joan Burton refused to speak with reporters questioning her on the motion of no confidence.
Gilmore's junior partner at the Department of Foreign Affairs, Joe Costello, also refused to express confidence in Tánaiste ahead of "a thorough, robust meeting" saying the matter would be discussed immediately.
