Other reaction: Minister for Enterprise Micheál Martin said former taoiseach Charles Haughey was the architect of Ireland's social partnership, which had contributed to several decades of stability in industrial relations.
He had also become the first minister to put the "tobacco issue" on the agenda, in terms of advertising controls, Mr Martin said in Galway.
Mr Haughey's "imaginative" approach had placed Ireland "ahead of Britain in terms of some welfare state provisions".
Mr Martin said that he had been a young TD when Mr Haughey was coming to the end of his political career, but he knew his sons, Ciarán, Conor and Seán, very well through his involvement with Ógra Fianna Fáil and was "very saddened" by his death.
Recent events and the "revelations in tribunals" had "created a picture that was upsetting to many of us who supported him", Mr Martin said. However, he would like to see the former party leader remembered as a "minister who wanted to make a difference rather than just be a minister" and a man who did not shirk from difficult decisions and the challenge of leadership.
• Barbara O'Neill, the founding president of the US fundraising group, Friends of Fianna Fáil, was expected in Dublin today to pay tribute to "the greatest Irish politician of the century".
Ms O'Neill, a first cousin of Mr Haughey, said that she would always remember his "wonderful sense of humour and his quick wit". She said she heard about Mr Haughey's death after getting a mobile phone text message from his son, Conor.
