At a press conference, Varadkar said he is resigning as president of the Fine Gael Party effective on Wednesday.

He said he will also step down from the prime minister role, known as Taoiseach, once a new leader is ready to take the role. An election will be held April 16.

Varadkar has served as Taoiseach since December 2022, and previously from 2017 to 2020.

Varadkar recently was in Washington, D.C., and visited the White House to celebrate St. Patrick’s Day with President Biden.

Varadkar used his remarks at the luncheon to thank the United States for its work to bring peace between Ireland and Northern Ireland — part of the United Kingdom — with the 1998 Good Friday Agreement. But he turned to the war in Ukraine, as the House has stalled in passing additional U.S. aid for the country.

“Ukraine must not fall and together, we need to stand by Ukraine for as long as it takes,” Varadkar said. “We look forward to working with America for the next 100 years.”

“Mr. President, as you know, the Irish people are deeply troubled about the catastrophe that’s unfolding before our eyes in Gaza, and when I travel the world, leaders often ask me why the Irish people have such empathy for the Palestinian people,” Varadkar added, according to the New York Times. “The answer is simple: We see our history in their eyes.”
