Businessman Peter Casey has announced that he is seeking a nomination to contest the Presidential Election.
Mr Casey, the founder of recruitment firm Claddagh Resources, is the third Dragons' Den entrepreneur to seek a nomination after Seán Gallagher and Gavin Duffy.
He lost out to Michael D Higgins in the 2011 election.
Speaking on RTÉ's Today with Miriam, Mr Casey said he would work at "activating the diaspora", creating a birthright programme and bringing attention to the salary of the President.
When asked if he had any plans to speak out about homelessness, Mr Casey said homelessness was a matter for the Taoiseach and for him to solve, but not a matter for the President to get involved in.
He said the role of the President was to be the guardian of the constitution and not to get involved in social issues.
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.
This afternoon councillors from local authorities in Cavan and Longford have put down motions to nominate Mr Gallagher for the presidency.
It brings to 12 the number of councils that have put down motions to nominate him since he announced his intention to seek a nomination yesterday morning.
Mr 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.
Meanwhile, Minister for Justice Charlie Flanagan has said it is possible for the new president to be inaugurated on 11 November and still attend ceremonies marking the centenary of the end of World War I.
Sitting President Michael D Higgins' term ends on 10 November, and the constitution requires a successor be inaugurated at the earliest opportunity, which is 11 November.
Mr Flanagan said "it is a coincidence of dates" that this coincides with the centenary of Armistice Day.
He added that the president, whoever it will be, may have a busy day on 11 November, beginning with the inauguration and then going on to the commemoration ceremony.
The minister also said that Fine Gael supports Mr Higgins' candidacy for a second term and he expects every part of the organisation, especially elected councillors, to fully comply with that decision.
Mr Flanagan also said the notion of not accepting a salary for the role, as suggested by Mr Casey, "demeans the office of president."
