While a number of people have expressed an interest in standing as independent candidates against current Irish President Michael D Higgins several more are expected to confirm over the coming days.
To gain a place on the ballot paper aspiring candidates need at least 20 signatures from TDs and Senators or by winning the backing of four county councils.
Michael D Higgins, thought to be all but sure thing, can automatically go forward as sitting president. Paddy Power bookmakers are currently offering odds of 1/4 for the incumbent to be returned.
Seán Gallagher, Irish entrepreneur and businessman came second in the 2011 Presidential election, has been given a 5/1 chance.
Gavin Duffy: A businessman and also a Dragons' Den panellist has already addressed a number of councils to secure support, he's at odds of 12/1.
Joan Freeman: The founder of Pieta House a mental health charity, has also lobbied councils, TDs and Senators to secure a nomination, is available at odds 25/1.
Kevin Sharkey: The Donegal artist and former TV presenter has called for a referendum on Ireland’s EU membership. He's a 100/1 outsider.
Sinn Féin have yet to announce its candidate, among the possibilities are the Munster MEP Liadh Ní Riada 33/1 and north Belfast solicitor John Finucane. 20/1
Pádraig Ó Céidigh: An Independent senator and Galway businessman, has yet to officially announced whether he will run. 66/1
