The Fianna Fáil TD managed to win back a seat for his party in the Dublin West constituency which was lost after the death of former finance minister Brian Lenihan in 2011.
Mr Lenihan, who was a friend of the family, inspired Mr Chambers to get into politics and he reopened the late politician’s constituency offices in 2014.
His articulate and informed approach on matters — he has spoken out strongly against any repeal of the Eighth Amendment — are sure to get him noticed within Leinster House and he is likely to be an important member of the party in the coming years.
Mr Chambers holds an honours degree in law and political science from Trinity College Dublin and has studied medicine at the Royal College of Surgeons in Ireland.
He was elected to Fingal County Council in 2014 and his speedy ascension to national office epitomises Fianna Fáil’s comeback since the disaster of the 2011 general election.
Speaking at the count centre shortly before he was elected, Mr Chambers said: “I think Fianna Fáil are back.
“This government wanted a coronation from the start, they had no vision, no energy, they just wanted to be re-elected without putting any positive platform forward.
“Micheál Martin led this campaign from the start and I think the people have had their say and Fianna Fáil are coming back having learned from their mistakes. They have a long-term vision for this country,” he said.
The first-time TD was born in Galway to Mayo parents but moved to Dublin West at the age of two. His parents were by his side at the count centre in Phibblestown as he celebrated winning a Dáil seat.
