There will be three candidates running in the Presidential election, following the closing of nominations earlier today.
Independent Catherine Connolly, Fianna Fáil's Jim Gavin and Fine Gael's Heather Humphreys will be on the ballot come polling day, after nominations closed at midday.
Barrister Maria Steen failed to secure enough support to join the race, securing 18 Oireachtas nominations when 20 was required.
Voting takes place in 30 days' time, on 24 October.
It is the smallest field in a presidential election since 1990.
After her campaign ended this morning, Ms Steen told the media that "rarely has the political consensus seemed more oppressive or detached from the public's wishes."

She added that she had sought the presidential nomination "in the hope of giving voters a real choice".
However, Taoiseach Micheál Martin rejected suggestions that the failure of Ms Steen to secure a nomination was "anti-democratic".
Speaking in the US, Mr Martin said: "It's quite extraordinary that the people who have been criticising Fianna Fail for quite a number of years, now expect us to support their candidate".
Having reached 17 nominations last night, Senator Aubrey McCarthy gave Ms Steen his backing this morning, bringing her to a final number of 18 - two short.
Senator McCarthy, the founder of the charity Tiglin, said the nomination was not an endorsement of Ms Steen, but that he believed she deserved the opportunity to make her case to voters and then voters will have the right to decide.
All three confirmed candidates on the ballot on RTÉ's Drivetime programme this evening.

Ms Humphreys said housing supply is "the biggest challenge" facing the country and "very tough", but stopped short of agreeing with outgoing President Michael D Higgins that it has become a "disaster".
In June 2022, President Higgins described the housing crisis as "our great, great, great failure" and a "disaster" for people affected by the situation.
Asked if she agreed with the comments, Ms Humphreys said "housing is the biggest challenge facing us".
She added "it is a huge, huge challenge" and "very tough" as "people are putting off decisions" in their lives, adding "we need to see results".
During the same interview, Ms Humphreys said while "some people might say" she is an "establishment" candidate due to her decade in various ministerial roles, she would instead describe that "as experience".
Independent Catherine Connolly, who has been backed by a host of left-wing parties, said being elected as the first female Leas Ceann Comhairle in Dáil history demonstrated her ability to attract votes from across the political spectrum.

Speaking on RTÉ's Drivetime, Ms Conolly said throughout her political career she has always appealed to people on every side.
"I think I showed that as Leas Ceann Comhairle. I stood and I was elected the first female Leas Ceann Comhairle.

"Baineadh mé úsáid as an ról sin chun an Gaeilge a chuir chun cinn an t-ám uilig," she said.
Ms Connolly added: "I did it as professionally as possible. I used the Irish language as naturally as I could during that role and I think I demonstrated my ability chaired Dáil and listen to opinions from every side. Many of them I didn't agree with."
The Galway West TD said it would be "an utter privilege to be President" and she is standing on the strength of her track record of her whole career.
Also on Drivetime, Fianna Fáil candidate Jim Gavin said he will not be directing his supporters to give their second preference to Ms Humphreys.

He said he was focused on his own campaign and his aim of becoming a positive voice in the Áras.
Asked repeatedly whether he would ask voters to give a second preference to Ms Humphreys, he said he would not be telling people what to do.
Mr Gavin said that he would host public forums at the Áras on various topics including homelessness, housing and the environment.
He also said that he would "shine a light on the great things we do in the country, but I will also highlight the vulnerable of our society".
