Current and former EU Commissioners David Byrne and Peter Sutherland are among the speakers who will address a series of public meetings on the Nice referendum planned by Fine Gael.
Former Taoiseach John Bruton said the party had also prepared a comprehensive question and answer sheet on the issues around the treaty, which the organisation would deliver across the country.
Mr Bruton said a No vote would mean Ireland had set itself on a course leading towards ultimate self exclusion from the EU. He said a Yes vote was vital for this and future generations of Irish people.
