Barry Cowen TD has called for special meeting of the Fianna Fáil parliamentary party to discuss the results of the Dublin Bay South by-election.
The Fianna Fáil candidate, Deirdre Conroy received just 5% of first preference votes.
The Labour Party’s Ivana Bacik topped the poll and was deemed elected on the final count.
Cowen described Fianna Fáil’s performance as “both a shock and alarming but strangely not hugely surprising.”
He said the matter cannot be ignored and called for an urgent special meeting of the party.
“Our parliamentary party, its leadership and executive personnel of the party should meet during the summer to reflect, discuss and take on board these messages,” Cowen said.
