Seán Gallagher is the first person to officially be named as a presidential candidate.
Wexford County Council was the fourth local authority to endorse the former Dragons Den star which put his name on the ballot paper.
Mr. Gallagher, who was the runner-up in the 2011 election, is now guaranteed a place alongside Michael D Higgins on the ballot paper on October 26th.
Roscommon County Council was the first to support the businessman, followed by Mayo, Leitrim and Wexford.
Anybody putting their name forward requires either the support of four councils or 20 members of the Oireachtas before they can secure a formal nomination.
Michael D Higgins, who has already confirmed his plan to run for a second-term, is able to nominate himself.
