Listowel town councillor Tom Walsh failed in his recent bid, at a convention, for a nomination to contest the upcoming local elections as a FF candidate in the Listowel electoral area.
Yesterday he confirmed he will stand as an Independent in the seven-seat area and claimed the party was in “total disarray” in north Kerry.
Mr Walsh said he was getting a positive reaction on the ground and was looking forward to his campaign.
The development is one of a series of setbacks for FF, which failed to win a seat in Kerry in the last general election.
Former FF senator and county councillor, Dan Kiely, has also left the party after failing to get a nomination, or to be added to the party ticket, and he is expected to stand as an independent in the Listowel area.
Former Killarney FF town councillor Tom Doherty will run as an independent in the Killarney area. He opted to go it alone for the same reasons as Mr Kiely.
In Tralee, Cllr Johnny Wall, a FF town councillor for 29 years, left the party earlier this week and may run as an Independent. He had also been defeated at a convention.
There was further disappointment in recent weeks, following a shock decision by outgoing councillor and FF whip on Kerry County Council, Paul O’Donoghue, a brother of former Cabinet minister John O’Donoghue not to seek re-election.
