Fianna Fáil deputy leader and former finance minister Brian Lenihan has died aged 52.
Mr Lenihan was diagnosed with pancreatic cancer in December 2009.
Brian Lenihan died in the early hours of the morning at his house in west Dublin.
He is survived by his wife, Patricia, their two children, his mother, and three brothers and one sister.
Details of Mr Lenihan’s funeral have been published.
Mr Lenihan will lie in repose from 10am on Monday at Jennings Funeral Home, Main Street, Blanchardstown Village.
Removal will be on Monday evening to St Mochta's Church, Porterstown, arriving at 6pm.
His funeral will take place on Tuesday, after 11am Mass, to St David's church graveyard, Kilsallaghan.
Brian Lenihan had a strong family tradition in Fianna Fáil. His father, Brian senior, was a leading figure in the party for many years, while his grandfather, aunt and brother were also Fianna Fáil TDs.
A barrister, Mr Lenihan was elected to the Dáil in 1996 for Dublin West in the by-election caused by the death of his father.
He was recognised as a talented TD, but promotion came slowly under Bertie Ahern's leadership.
After a spell as Minister for Children, he finally became a full member of Cabinet as Minister for Justice in 2007.
Less than a year later, new Taoiseach Brian Cowen appointed him Minister for Finance.
He famously pointed out at the time that he had the 'misfortune' to take up the post just as the building boom was coming to a shuddering end.
That economic turnaround, coupled with the collapse of Lehman Brothers in the US, threatened Irish banks.
After a tense night of meetings in Government Buildings in September 2008, the Government guaranteed €400bn of loans and deposits for Irish financial institutions.
Later, NAMA was set up to absorb property loans, most banks were effectively nationalised, and a series of tough budgets were introduced, cutting spending and raising taxes.
In January 2010, it was confirmed that he was suffering from cancer, but he continued on in his job.
He unsuccessfully contested the Fianna Fáil leadership after Brian Cowen's resignation and was the only Fianna Fáil TD elected in Dublin in February's General Election.
Since then, he has been deputy leader of the party, as well as Finance Spokesman, but in recent weeks his health again deteriorated.
A book of condolence will be opened at Mr Lenihan’s constituency office at Laurel Lodge Shopping Centre in Castleknock, Dublin 15 tomorrow from 1pm to 6pm.
Micheál Martin deeply saddened
Speaking on RTÉ's Radio One, former TD and Mr Lenihan's aunt Mary O'Rourke said: 'It's all over. It's kind of unbelievable.'
'He always worked for his country and he worked for the best of Ireland and I suppose in the end what anybody in public life would wish to do, and that's what he did.
'I just feel my life has almost ended, I really do.'
Taoiseach Enda Kenny described Mr Lenihan as a decent man and exemplary public servant.
'Brian Lenihan was exemplary in the carrying out of his public duties.
'He continued a long line of representation for Ireland in public life by both his father (Brian) and grandfather (Patrick) and his family in general,' he said.
'He exemplified a great sense of humanity in the public representation he gave.
'I'd like to say I've known Brian Lenihan for many years and regard him as a friend in politics,' he added.
Fianna Fáil leader Micheál Martin said he was deeply saddened by Mr Lenihan's passing.
'Brian has fought a brave and courageous battle with a serious illness over the past 18 months,' he said.
'In all of this time, Brian never once flinched from his public duties and he showed an unceasing and untiring commitment to tackling the economic crisis facing this country.
'Even when receiving debilitating treatment, Brian continued to work assiduously in the best interests of this country. For Brian Lenihan, that was always paramount.'
