Enda Kenny has announced that he will step down as leader of the Fine Gael Party on Wednesday night.
Mr Kenny announced he will step down as Fine Gael party leader as of midnight tonight, although he will stay on as Taoiseach until a successor is elected.
He announced past year that he would not lead Fine Gael into another election but has delayed his resignation several times in recent weeks amid discussions about Brexit in Brussels.
The small opposition Greens called for the new prime minister to be in place by the June 22 gathering of European Union leaders.
Kenny said Fine Gael would name his successor no later than June 2. "I hope now Leo goes on to win this Fine Gael contest".
"I also believe Minister Varadkar will help stabilise our country, deal with the challenges of Brexit and help Donegal and the border counties in the months and years ahead".More news: Senate intelligence committee wants information on Trump's meeting with Russians

One TD said it was the "shortest ever" party meeting with the remaining agenda abandoned as members spilled onto the Leinster House plinth to discuss Mr Kenny's legacy.
Kenny, prime minister since 2011 and leader of his party for nearly 15 years, is expected to be replaced by either Leo Varadkar, the social protection minister, or Simon Coveney, the housing minister.
Meanwhile, Minister Varadkar has received the backing of the Minister for Education and Skills, Richard Bruton. His main challenger will be Simon Coveney, Ireland's Minister for Housing, Planning, Community, and Local Government.
So, scroll back up and vote for who you would pick as the next Fine Gael leader and likely taoiseach. "That is precisely what we need right now and I believe Simon Coveney will deliver on this", Mr Harris said. He said he contacted Mr Coveney yesterday morning to inform him of his decision but was not able to reach Mr Varadkar.
