US president Donald Trump said Irish unity would be a “great thing” in response to a reporter’s question on his visit to Dublin.The comments, made alongside Taoiseach Micheál Martin at Farmleigh, caused eyebrows to be raised north and south of the Border and in London, but they were subsequently downplayed by a spokesperson for the Taoiseach who made it clear that Ireland’s policy on the North had not and would not be changing. A spokesman for British prime minister Andy Burnham said there was no majority support for a referendum and that one will not be held until that changes.DUP leader Gavin Robinson said Northern Ireland’s constitutional future “will be decided by the people of Northern Ireland, not by commentary in London, Dublin or Washington”.“As unionists we are not interested in the destruction of our country by joining with the Irish Republic,” he said.Sinn Féin president Mary Lou McDonald acknowledged the remarks, but focused in her statement on calls for the US to “stop facilitating the genocide of Palestinian people”.The US president’s flying visit to Dublin passed off without further controversy.President Catherine Connolly greets US president Donald Trump at Áras an Uachtaráin.

All three engagements took place within the Phoenix Park in Dublin.Trump told reporters at Farmleigh he had discussed Northern Ireland with Connolly during their private meeting in Áras an Uachtaráin and said it was a topic that was of great interest to him. Almost immediately he was asked for his views on a united Ireland. “I’d love to see it unified. It is going to happen eventually. You have the right man over here to get it moving,” he said, gesturing to Martin. “I think it would be a fantastic thing. I think the UK would have something to say about it but I think it would be a great thing. How could it be bad?”The No Welcome for Trump demonstration in Dublin city centre on Saturday.

Trump described it as “a very nice meeting”, adding that he had considered it “respectful”.In a subsequent statement, Connolly said she had “conveyed the strong view of the Irish people that the normalisation of war and genocide can never be accepted” and “emphasised the unique insight which Irish people can bring to the resolution of conflict”.US president Donald Trump and Taoiseach Micheál Martin at Farmleigh on Saturday.
