Fianna Fáil's John McGuinness has said voters want his party to "have the back bone" and confront the Government where it fails rather than continuing the Confidence and Supply Agreement for another two years.
Speaking on RTÉ's Today with Sean O'Rourke, Mr McGuinness said he is not in favour of continuing the agreement beyond its current time frame as he believes it "has not served the country well".
The Carlow-Kilkenny TD said all of the issues that existed when the agreement was put in place three years ago have worsened.
He said Fianna Fáil needed to confront the Government on this.
He said the agreement was not delivering for people and it meant Fianna Fáíl could not fully confront the Government on issues with the agreement still in place.
He said an election would result in a new direction, with a government that will take decisions.
Mr McGuinness said Taoiseach Leo Varadkar is suggesting in his letter that there are a significant number of areas that can be discussed in the context of the Confidence and Supply Agreement but "let’s not do this in the light of Brexit".
Brexit is a serious threat to Ireland but also a threat is that there are so many people suffering because of the "poor policies" of this Government, he said.
He continued that Fianna Fáil is condoning it by giving them the protection of the Confidence and Supply Agreement.
Both Fianna Fáil and Fine Gael are looking at the possibility of an election, he said, because the agreement is coming to an end.
He said both party leaders are facing off against each other and "a bit of shadow boxing is going on".
Minister for Agriculture, Food and the Marine Michael Creed has reiterated that Fine Gael does not want a general election.
Speaking on the same programme, Mr Creed said the Confidence and Supply Agreement between Fianna Fáil and Fine Gael has worked for the public.
He said there was no guarantee that if there was an election, the current parliamentary arithmetic would change, in fact he said he believed no one would get an overall majority.
