US President Barack Obama is planning a massive rally on O'Connell Street in Dublin during his 24-hour visit to the Republic later this month, it can be revealed.
Mr Obama is understood to be keen to address a large public gathering during his whistle-stop tour.
But the tight schedule means that the plans are repeatedly changing.
The latest draft includes a public speech on O'Connell Street on the evening of Monday, May 23, an Irish government source said.
The President will also meet Irish President Mary McAleese and Taoiseach Enda Kenny, along with a visit to his ancestral home in Moneygall, Co Offaly.
Mr Obama is known to be a fan of Daniel O'Connell, largely because of his opposition to slavery.
“He wants to do a public event and the Americans like the idea of O'Connell Street as the symbolic heart of Ireland. He is a big fan of O'Connell,” the source said.
This is the latest plan, subject to security and logistical clearance, the source added. Holding a rally to be attended by thousands of people in Dublin would present enormous security issues.
Mr Obama will arrive in Dublin on May 23 with a packed schedule before he heads to London the following day on a state visit hosted by the Queen.
During one of his visits to the White House, former Taoiseach Brian Cowen referred to O'Connell's rallies in the mid 1800s.
He drew comparisons with Mr Obama's ability to draw large crowds wherever he spoke.
