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.
Eamon Dooley, a Fianna Fáil member of Offaly County Council, has confirmed that eight councillors have submitted a motion to nominate Mr Gallagher at a special meeting of the council on 10 September.
Fianna Fáil Councillor John Paul Feeley has said that he has submitted a motion to Cavan County Council to nominate Seán Gallagher.
The Presidential Election will take place on 26 October. Nominations have to be submitted by 26 September.
Those hoping to be candidates require the support of four local authorities or the backing of 20 members of the Oireachtas.
The sitting president can nominate himself and President Higgins is seeking a second term.
Sinn Féin has also said it will field a candidate.
So far, Gavin Duffy, Patrick Feeney, Joan Freeman, John Groarke, Marie Goretti Moylan, Sarah Louise Mulligan, Gemma O'Doherty, Kevin Sharkey and James Smyth have appeared before local authorities seeking a nomination.
