Tributes have been paid to former junior minister and key Northern Ireland peace process adviser Martin Mansergh, who has died aged 78.
Taoiseach and Fianna Fail leader Micheal Martin said he learned of the passing of the former TD and Senator with “deep sadness”.
Mr Mansergh had been on a trip to the Sahara with other retired parliamentarians at the time of his death.
Mr Martin said: “I had the honour of knowing Martin for over four decades.
“He was unquestionably one of the most important public servants in our recent history, filly many different roles and having a profound impact on issues deeply important to the Irish people.”
Mr Mansergh served as an adviser to leaders of Fianna Fail, both in government and in opposition.
Mr Martin said he was “exceptional in his knowledge and devotion to the cause of peace” on the island of Ireland and throughout Europe.
He added: “His contribution to securing peace on this island mark him as a figure who will always be honoured.
“His early, secret negotiations in Belfast on behalf of Taoiseigh and his work through more than a decade were essential in securing the peace settlement and the overcoming of many later hurdles.”
Mr Martin, who expressed sympathies to Mr Mansergh’s wife Elizabeth and the rest of his family, said: “Martin was a one-off, a true Irish republican. A man of great accomplishments who leaves a proud history”.
Northern Ireland First Minister Michelle O’Neill said she was “deeply saddened” to learn of the death of Mr Mansergh.

“Martin played a key role, particularly in the early stages of the Irish peace process and in the later development of the Good Friday Agreement,” she said on X.
“I extend my heartfelt sympathy to his family, friends and his colleagues in Fianna Fail.”
Meanwhile, Tanaiste and Fine Gael leader Simon Harris also expressed his “deepest condolences” to Mr Mansergh’s friends, family and colleagues.
Mr Harris said Mr Mansergh had played an “instrumental role” in drafting amendments to the Constitution which was part of the ratification of the Good Friday Agreement in the Republic of Ireland.
“Few people were as consequential in shaping Irish Government policy on Northern Ireland and few on the Irish side were more crucial to the peace process, whether through his role as an intermediary or his work to craft a new political and intellectual framework for peace.”
He added: “On a personal level, I knew Martin to be warm, generous with his time and insights, and a person of great integrity with an incredible commitment to peace on our island.”
Former Sinn Fein leader Gerry Adams expressed condolences to the Mansergh family and Fianna Fail.
In a statement, he said: “Martin Mansergh was a key figure in the efforts to build the peace process and the success of the negotiation leading to the Good Friday Agreement.
“He was one of those who met with Sinn Fein in the late 1980s on behalf of Fianna Fail and we retained a close relationship since then.
“Martin served a number of Taoisigh and his crucial role, along with other senior government officials, and John Hume, and Sinn Fein representatives, was in the build-up to the negotiations at Good Friday in 1998 and in the work that was done after that.
“I value very much the numerous engagements that we had and the relationship that we developed as a result of that.
“I wish to extend my sincere condolences to his wife Elizabeth and his five children.”
