Independent minister of state and Waterford TD John Halligan has confirmed he will not contest the general election.
The Independent Alliance politician said he is retiring from political life, and now wants to devote more time to his family.
In a statement, Mr Halligan said: "It has truly been a profound honour to represent the people of Waterford at both local and national level throughout my career.
"I have served every single day in public office fighting for what I believed was right and working with determination on behalf of my constituents."
He added: "Most of all I want to humbly thank the people of Waterford who have put their faith in me for these past three decades.
"Together we have experienced many highs and lows down through the years. We have endured trying times as a city and county but have held fast in the spirit of community and emerged stronger for it."
Mr Halligan drew media attention on a number of occasions during his time in government - including over his proposal for a peace mission to North Korea.
The Waterford politician's announcement this morning comes after his fellow Independent Alliance member Finian McGrath also confirmed he would not be standing in next month's election.
Kevin 'Boxer' Moran is also leaving the Alliance - meaning Sports Minister Shane Ross is the group's sole remaining member contesting the election.
