Labour: Labour Party leader Pat Rabbitte paid tribute to Mr Haughey's achievements, parliamentary skills and reforming record, saying that this was not the time for a full assessment of a political legacy that included "a darker side".
He said that in and out of office, Mr Haughey had been a dominant figure in Irish politics for almost four decades.
"He was at all times a hugely controversial figure who attracted great loyalty among his supporters and fierce opposition from his opponents. As taoiseach and as a government minister, Charles Haughey had many achievements of note. He was a skilled parliamentarian and a genuinely reforming minister for justice and minister for social welfare.
"There was probably no other Irish politician over the past 50 years who was such a controversial figure and there is a darker side to the Haughey political legacy," he said.
Now was not the time "for a full political assessment of the career of a man who has endured such a painful and debilitating illness in recent years. I extend my sympathy to his widow, Maureen and to his children, Conor, Ciarán, Seán and Éimear."
