The man in his 70s killed in a crash in County Roscommon is former TD and Senator John Connor.
The Taoiseach Leo Varadkar has expressed his condolences on his death over the weekend.
The Taoiseach says he's "deeply shocked and saddened" to hear of the passing of John Connor.
The car the former TD and Senator was driving crashed on a local road in Frenchpark on Saturday afternoon.
Leo Varadkar says John represented the Roscommon area for Fine Gael for over three decades, as a TD, Senator and Councillor.
He was first elected TD for the Roscommon East Galway constituency in June 1981.
He lost his seat in the General Election of 1982, but was nominated to the Seanad in 1983 by then Taoiseach Garret Fitzgerald, where he served on the Agriculture panel.
The Taoiseach says John had an unwavering commitment to the people of his area and brought a considerable expertise to politics at local and national level.
