Enda Kenny congratulates Donald Trump on election victory
Enda Kenny has said he is confident relations between Ireland and the US will continue to prosper under Donald Trump's leadership.
The Taoiseach vowed to work with the new administration in Washington "in the cause of international peace and security".
"On behalf of the Government and the people of Ireland, I am pleased to offer our sincere congratulations to Donald J Trump on his election as the 45th President of the United States," he said.
"Ireland and the United States have enjoyed a very close and warm relationship for many generations and I am confident that under his leadership our bilateral relations will continue to prosper."
Earlier this year, Mr Kenny had described remarks by Mr Trump during the presidential campaign as "racist and dangerous"..
In a statement following the US election result, Mr Kenny praised defeated candidate Hillary Clinton for being "a friend to Ireland who fought such a tough campaign".
He added: "We are all acutely conscious of the particular responsibility of the United States for leadership and engagement across the globe in our endeavours to address shared challenges.
"I look forward to working with the new administration in the time ahead in the cause of international peace and security.
"I also intend to work closely with the new administration and newly-elected United States Congress to pursue comprehensive immigration reform, an issue that is so important to tens of thousands of Irish people who are making a major contribution to America."
Mr Kenny also congratulated the new Vice President-elect Mike Pence who, he said, "is a proud Irish American who spent many summers in Ireland as a child".
Ex-Taoiseach Bertie Ahern said: "I think from our point of view, we need to have a bit of a love-in with his people very quickly.
"To the best of my knowledge, and I still visit the US a bit, we don't have any connections with his team.
"When he was going to come here some months ago, when he was in Scotland during the campaign on his business interests, as far as I could read between the lines, it was probably made clear to him he would get a hostile welcome here, so that was dropped off the itinerary."
Mr Trump cancelled a planned stop-off at one of his golf resorts in Doonbeg, Co Clare, in June.
Mr Ahern said the new president probably did not believe he would win and would now have to get a team around him and "play ball" with his Republican party colleagues to get things done.
