Reaction:The Taoiseach and Opposition leaders expressed shock at the death of Liam Lawlor and sympathy to his family, with Mr Ahern paying tribute to "an engaging, witty and larger-than-life character".
Mr Ahern said he was shocked to learn of the death of Mr Lawlor, whom he had known since the two of them were first elected to the Dáil in 1977.
"In his youth Liam was well known as a hurler of some renown and he represented Dublin and Leinster with distinction. He followed the route travelled by a number of many prominent GAA stars and swapped the playing pitches for political life. Liam was elected as a TD for the constituency of Dublin West and during a 25-year career in politics he was an assiduous worker on behalf of his constituents.
"In volatile political times in the 1980s, Liam lost his seat on two occasions, but each time regained it in the following election. Liam announced his retirement from politics prior to the general election in 2002."
The Taoiseach said Mr Lawlor had a keen intellect and strong views "that he was never afraid to articulate trenchantly. Outside the rough and tumble of political activity, he was extremely popular with his parliamentary colleagues across the political board.
"At this difficult time, my thoughts are with Hazel and all Liam's family especially his daughter, Ciara, who worked with me during my time as leader of the opposition."
Fine Gael leader Enda Kenny also expressed sympathy to Mr Lawlor's family.
"On behalf of the Fine Gael party I extend my deepest sympathy to Liam Lawlor's wife Hazel and their children."
Tánaiste Mary Harney said she had learned of his death with great regret. "To lose his life in an accident so far from home represents a terrible tragedy for his family and friends."
She expressed her sincere sympathy to Mr Lawlor's widow and their children.
Labour Party senator Joanna Tuffy also expressed her sympathy and that of the Labour organisation in Dublin Mid West, which borders Mr Lawlor's Dublin West constituency.
"Although a controversial political figure, Liam Lawlor was a diligent representative of the people of this area for many years. He was also invariably courteous in his dealings with other public representatives in the area.
"I want to extend my sympathy to Liam's widow Hazel, his family and his friends on their sad loss."
Green Party leader Trevor Sargent said: "Although in recent years he was known for controversy, Liam Lawlor was always personable in the Dáil and took trouble to see what topics were of interest to new TDs which he would then introduce into any conversation. He generally liked to discuss Sellafield whenever I met him.
"I wish to extend my sympathies to his widow Hazel, his children, family and friends at their sudden and sad loss."
