Independent candidate Catherine Connolly has increased her lead in the Presidential Election, a new Business Post/Red C poll suggests.
The survey puts Ms Connolly's support at 44% - up eight points on a poll conducted nearly two weeks ago.
Fine Gael candidate Heather Humphreys is on 25% support - unchanged.
Jim Gavin, who pulled out of the election but whose name remains on the ballot paper, is on 10% - down two points, albeit that Mr Gavin was still campaigning during some of the previous poll fieldwork.
A substantial 21% remain undecided - down six points on the previous poll.
Once undecided voters are excluded, the poll shows Ms Connolly on 55% with Ms Humphreys on 34% and Jim Gavin on 11%.
The margin of error in the poll is +/-3%.
The online survey of 1,012 people was conducted on dates between 16 to 21 October.
The two candidates for the presidency have been making late pushes for votes as they campaign across the country.
Fine Gael candidate Heather Humphreys canvassed in counties Cork and Clare today, while Independent Catherine Connolly was on the stump in Cavan, Monaghan and Westmeath.
Ms Humphreys began campaigning in Cork's South Mall, before moving on to the Arts and Heritage centre in Mitchelstown and then campaigning on the streets of Ennis.
Ms Connolly was in Monaghan before travelling to Cavan, then Athlone and ending with campaign supporters and Palestine activists in Mullingar.
Speaking at a rally in Monaghan, Ms Connolly denied assuming she would win the election, stating she was taking "nothing for granted".

Updates as they happen
Both candidates participated in the final TV debate of the election last night, on RTÉ's Prime Time.
Last night's debate covered many themes of the presidential election campaign in great detail, and both candidates stuck to their long-held positions.
Ms Humphreys engaged in intense discussion over the 70 minutes, but there was no clear indication by the end of the programme that she had changed the dynamic of a contest.
Galway West TD Ms Connolly launched her Future Voices initiative during the rally in Monaghan town.
She was asked about comments during the debate when she said "when" rather than "if" she wins Friday's vote.
Ms Connolly was asked if she was taking victory for granted.
She said: "I am absolutely not taking it for granted, absolutely not.
"It will be an absolute privilege if the people of Ireland elect me when they cast their vote on Friday.
"I am taking nothing for granted, I am canvassing the rest of the day and tomorrow."
Ms Connolly added: "I think we had three hours' sleep last night.
"I am not complaining, I am simply explaining that that is the nature of the campaign."
She said that if she does win the race for the Áras, it sends a strong message to the Government.
"I hope it sends a very positive message that they should reflect on the way they have approached this campaign.
"Also, there is a gap between what the Government are seeing and what people are seeing on the ground.
"You can see it everywhere we go that people are crying out for honesty, integrity and for a different vision for the country and for a solution to our problems," she said.
Ms Connolly has received support in her campaign from Sinn Féin as well as a number of smaller parties.
Sinn Féin vice president, and Northern Ireland's First Minister, Michelle O'Neill, was in Co Monaghan to support Ms Connolly.
Ms O'Neill said Ms Connolly's campaign had given people hope.
She added: "I think what we are saying over the course of this campaign marks a change in Irish politics.
"It very much marks a new beginning and that is something that we all want to see."
She added: "I think you have reminded everybody what politics is all about and that is the service of people, giving people hope.
"Never ever has there been a time when we more need to see that independent vote in the Áras."
Ms O'Neill also said it had to be last Irish presidential vote in which people from Northern Ireland were not permitted to vote.
Fine Gael's Director of Elections Martin Heydon described online attacks on Ms Humphreys' background as "wedge politics at its worst".
Mr Heydon said there has been a lot of sectarian content about the party's candidate and her family online.
"I don't know Catherine Connolly's family circumstances. I don't know if she is marred, if she has kids. I don't care, it's not part of it, but I haven't read anything about it on social media.
"I've read some very sinister comments about Heather Humphreys, her family, her culture, her tradition, and its wedge politics at its worst."
"It is concerning in terms of the context of what people consider to be the right approach for a united Ireland, and in terms of uniting people," Mr Heydon said.
Tomorrow will be the final day of campaigning, with voters going to the polls on Friday to elect a successor to outgoing President Michael D Higgins.
