The deaths of former Fianna Fáil minister Noel Davern and ex-TD Denis Foley have been announced.
Mr Davern who was 67 had been a TD for South Tipperary and a Member of the European Parliament.
He was Minister for Education in 1991-92 and also served as Minister of State at the Department of Agriculture.
He is survived by his wife Anne Marie and children Don, Marc and Davina.
Denis Foley who was 79 served several terms as TD for North Kerry after being first elected in 1981.
Mr Foley was defeated in the 1989 Dáil election but was elected to the Seanad before winning back his seat in 1992.
From 1995-1997 he chaired the Public Accounts Committee and was Vice-Chairman from 1997 to 2000.
Mr Foley resigned from Fianna Fáil in 2000 after it was revealed he held an Ansbacher offshore account.
He is survived by his wife, Hanna, and four children, Billy, Norma, Margaret, and Denise.
Fianna Fáil leader Micheál Martin paid tribute to both men.
He said he was shocked to learn of Mr Davern's sudden death.
"Noel was known in politics for his kind nature and good sense of humour. He was a passionate public servant who never shied away from representing his constituents at a local, national or European level," said Mr Martin.
Paying tribute to Mr Foley, he said he was a "tireless champion for the interests of his Kerry constituents".
"I was saddened to learn of the death of former colleague Denis Foley. Denis represented the people of Kerry North as a Fianna Fáil representative for almost twenty years with diligence and great commitment.
"During this time he worked with colleagues from all parties to advance the interests and issues of his community," said the Fianna Fáil leader.
