Presidential hopeful Sean Gallagher has revealed he was involved with Fianna Fail up to nine months ago.
The independent candidate admitted he only officially resigned from the party's National Executive last January.
The entrepreneur said he joined the highest organisational body of the party in 2009 to advance his proposal for legislation to protect sub-contractors when developers went bust and attended just two meetings, in July and December.
"In September 2010, Sean Gallagher verbally indicated to Fianna Fail headquarters that he would resign from the National Executive," said his spokeswoman.
"As the membership of the National Executive changes with each Ard Fheis, Sean intended to resign at this point.
"When it became apparent that no Ard Fheis was imminent, Sean confirmed in writing, with a formal letter of resignation, what had already been agreed in September 2010."
Mr Gallagher, who has worked with charity, voluntary and community groups throughout the country, gained national prominence after appearing as a judge on RTE's Dragons' Den.
He had also managed the election campaign of former Ceann Comhairle Seamus Kirk in 2007.
If elected, he has promised to use his business links to help boost job creation.
