Businessman Seán Gallagher has announced that he is going to seek a nomination to run for the presidency for a second time.
He said he intends to seek a nomination from four local authorities.
Mr Gallagher lost out to Michael D Higgins in the 2011 election, securing more than 500,000 first preference votes.
A website domain "seangallagher2018.com" was registered over the summer.
In 2017, RTÉ apologised to Mr Gallagher and paid him damages in settlement over a tweet read out on a live televised debate during the 2011 presidential election campaign.
The tweet purported to be from an account linked to the Sinn Féin candidate in the election, Martin McGuinness.
The account was not the official McGuinness campaign one.
In a statement, Mr Gallagher said Ireland is changing and the next president needs to provide a fresh approach at this important juncture for the country.
He said said some councillors in ten local authorities have put down motions to nominate him over the last 24 hours.
